A student titrates 20.0 mL of 1.0 M NaOH with 2.0 M formic acid, HCOOH (K, = 1.8 x 10 4). Hypochlorous acid is an unstable compound and one of the decomposition products is chlorine gas, Cl2. The composition of the acid lowers its concentration over time. What effect will the decomposition of one-fourth of the acid have on the agreement between the endpoint of the titration and the equivalence point during a titration with standard sodium hydroxide?

A student prepared two solutions: 1 @ (water + cabbage extract) and 1 @ (buffet + cabbage extract). The student adjusted the solutions to pH = 7 but forgot to label each of them so both were indistinguishable. The student decided to test one of the two solutions and split the solution into two beakers: Sol1 and Sol2. The student was really struggling that day and forgot to label the HCL and the NaOH solutions. Continuing with the experiment, the student added SolA into Sol1 and the color turned light red. What is the identity of SolA? What will the color of Sol2 be after SolB is added? What must the initial solution contain?
For a titration to be effective, the reaction must be rapid and the yield of the reaction must essentially be 100%. Is Kc > 1, < 1, or ≈ 1 for a titration reaction? Kc is the product of all reaction products (choose from: Multiplied by, added to, divided by, subtracted from) the product of the reactants, with all concentrations of reactants and products raised to their respective stoichiometric powers. As the titration proceeds, the amount of reactants (choose from: Increases, decreases, remains the same) and the amount of products (choose from: Increases, decreases, remains the same). Because the value of the numerator is (Choose from much greater than, much less than, approximately equal to) the value of the denominator, the value of Kc will be (Choose from much greater than, much less than, approximately equal to)1 for an effective titration reaction.
