Titrations (part 3) In this video we now have an equal amount of our acetic acid and our base -OH. This is called the equivalence point. -OH is a strong base so it will react with 100% yield. This is a fancy way to say that it reacts until it’s completely used up. Seeing as we have 1M of both our acid and base, at the end of our reaction we will have 0M of both! What’s produced from this reaction? We have 1M of our conjugate base CH3COO- This 1M of CH3COO- will now do a second reaction! It will react with water to produce hydroxide (-OH). From here we can find the pOH. Once we find the pOH we can do 14-pOH = pH #premed #mcat

Now "SAY MY NAME😎" A titration test is a quantitative chemical analysis method used to determine the unknown concentration of an identified analyte by reacting it with a standard solution of known concentration (the titrant). The titrant is added slowly from a burette until the reaction reaches its equivalence point, often signaled by a color change from an indicator .   Key Components and Process Titrant: A solution of known concentration and volume, usually placed in a burette. Analyte (Titrand): The solution with an unknown concentration, placed in a conical flask. Indicator: A chemical added to the analyte that changes color at the endpoint (e.g., phenolphthalein or methyl orange). Equivalence Point: The theoretical point where the stoichiometric amount of titrant has been added to react completely with the analyte. Endpoint: The physical, observable change (color change) that indicates the titration is complete.  Steps to Perform a Titration Preparation: Fill a burette with the titrant, noting the initial volume. Sample Preparation: Measure a precise volume of the analyte (unknown) into a conical flask using a pipette. Indicator Addition: Add a few drops of an appropriate indicator to the flask. Titration: Slowly add the titrant to the analyte while swirling the flask until the indicator changes color permanently. Recording: Record the final volume on the burette to calculate the amount of titrant used. Replication: Repeat the process to get concordant results (consistent, similar volumes).  Common Types of Titration Acid-Base Titration: Determines the concentration of an acid or base by neutralizing it. Redox Titration: Based on an oxidation-reduction reaction between the analyte and titrant. Complexometric Titration: Based on the formation of a complex between the analyte and titrant.  Safety Measures Titration often involves corrosive or toxic materials, requiring the use of safety goggles, gloves, and laboratory coats to prevent skin contact or inhalation.

Titrations are an important tool for the determination of unknown concentrations of solutions by using solutions of known concentration and indicators. The basic premise is that, if we add one solution to another gradually, eventually we will reach some form of 'balance point' or 'critical point' where a very clearly noticeable chemical/physical change occurs. The known solution is called the tytrant and the unknown solution is called the analyte. The titrant is added to a given volume of analyte dropwise, almost always via burette, and the final volume of titrant added when the special point occurs is measured. For acid base reactions, this could be the neutralization point, as in the balance point. At this point, the amounts of acid and base molecules is such that a balanced chemical reaction between them can occur. The pH will be close to 7 (Neutral) when this occurs. A pH indicator can be used in these cases to determine the volume of solution A added to solution B at the moment the two balance. For redox reactions, if there is a visible color change, like in KMnO₄ to Mn²⁺, you may not need external indicators. In other cases, an indicator substance that will either react with one of the reactants or products to produce a visible color change may be used; for example, starch to indicate the presence of iodine. When performing these titrations, it is important to add the titrant slowly, to make sure you measure the exact balance point and do not overshoot the correct titration volume. If you miss the balance point,either through lack of attention or paitience, you will be forced to forfeit that attempt and restart with a new titration. Here the student has done that four times and is frustrated. If a student has a rough idea of what the correct volume of the titrant to be added to achieve the balance point is, they may skip doing the titration altogether and simply input their false data as results from the titration. This is what the student does. It is sometimes effective, especially if the teacher gives a round number as the expected answer.

which factors influence the stability of a conjugate base? (hint: it's all of them but ig you could pick your favorite) footage sources: Bio-Rad Laboratories Titration of Acids and Bases, Wits University Official What is a Titration and how is it performed?, and various successful and unsuccessful titration images i found (we have not done titration yet this year so no fresh photos) text from libretexts, Chem 1202 at Mount Royal University. "The Arrhenius definition of an acid as a compound that dissolves in water to yield hydronium ions (H3O+) and a base as a compound that dissolves in water to yield hydroxide ions (OH-). This definition is not wrong; it is simply limited. We extended the definition of an acid or a base using the more general definition proposed in 1923 by the Danish chemist Johannes Brønsted and the English chemist Thomas Lowry. Their definition centers on the proton. A proton is what remains when a normal hydrogen atom,, loses an electron. A compound that donates a proton to another compound is called a Brønsted-Lowry acid, and a compound that accepts a proton is called a Brønsted-Lowry base. An acid-base reaction is the transfer of a proton from a proton donor (acid) to a proton acceptor (base). We call the product that remains after an acid donates a proton the conjugate base of the acid. This species is a base because it can accept a proton (to re-form the acid). In these two sets of equations, the behaviors of acids as proton donors and bases as proton acceptors are represented in isolation. In reality, all acid-base reactions involve the transfer of protons between acids and bases." #genchem #acidsbases #titration #chemist

In this video I walk through an acid base titration from start to finish and show you exactly how to turn experimental data into the correct answer. We cover what is happening chemically during neutralisation and how to use the titre value along with the balanced equation to calculate moles with precision. I also explain why the mole ratio from the equation is the key step that links your two substances together and where students most commonly lose marks. Hope this helps. – Bipan aka @thealevelexaminer #ALevelChemistry #ChemistryTutor #ChemistryExaminer

Anhydrous compounds. • copper (II) sulfate CuSO₄·nH₂O, is a hydrated copper salt, with the •n denoting the amount of water molecules in a coordination complex around the central metal ion. The most common is the pentahydrate that I have here, CuSO₄·5H₂O. The water ligands are the reason for the blue colour of the compound in both its solid hydrated state and it’s aquo complex in solution, absorbing red light and re-admitting blue light. • Four of the five ligand water molecules are formed around the central copper cation, with the final one interacting through hydrogen bonding. As cupric sulfate is heated, it starts to decompose, losing water molecules. The first two are lost at 63°C, the next two at 109°C and the final one at 200°C. At these points the blue colour is lost until we have a dirty white colour. • At this point we have anhydrous copper (II) sulfate, CuSO₄. The copper cations and sulfate anions now alone together in an orthorhombic fashion, hence the chemical formula with no mention of water. Water loves being a monodentate ligand though, and reintroduction of water to the now colourless solid allows water molecules to move into the ionic lattice, quickly reforming its coordination complex with copper cations and as such, bringing the blue colour back. #chemical #chemist #copper #sciencecommunication #science
