Your Name: Hannah McElhinneyDate experiment performed: 2/28/20Lab Partner: n/aName of Lab: Chemical EquilibriumLaboratory Notebook/Proof of Experimentation
Pre-Lab Questions:1.Differentiate between Kp and Kc.Kp is used with gasses and is related to Kc (Keq for concentrations) by the equationKp=Kc(RT)^(DeltaN)2.Describe the acid ionization constant. Ka (the acid ionization constant) describes how much acid dissociates in solution.
3.Describe the base ionization constant. Kb (the base ionization constant) describes how much base dissociates in solution.
4.
Purpose:We are performing this lab to explore equilibrium constants, to observe acid-base titrations and the equivalence point using aTumeric indicator. We will be starting with our 4.5% Acetic Acid and Tumeric indicator in distilled water mixture and then slowlyadding drops of 0.1M Sodium Hydroxide. Then we will be adding 8 drops (equaling approximately .5mL) of Sodium Hydroxide and
then recording the pH level of the acid-base solution. During this process we will be watching for the solution to change color which
