CHEM 104 Experiment 2 Equilibrium Reactions - Portage Learning The purpose of this experiment is to evaluate and study the equilibrium by measuring the equilibrium constant. Procedure: We performed 2 different experiments: o Determination of the equilibrium constant Kc o Study of LeChatelier’s principle Experiment #1: acetic acid vs. propyl alcohol 1. Summary: After gathering supplies, we created a solution of acetic acid and propyl alcohol in a small flask. At various time intervals, we then...

Practicals Chemistry AQA A-level Rated A+ Required Practical 1 - titration and making a standard solution Making a standard solution 1. weigh the required mass of solid using a sample bottle on a 2 dp balance. 2. transfer the solid into a beaker using distilled water to wash it out- preventing any solid remaining in the sample bottle. 3. reweigh the sample bottle and work out the difference. 4. Add 100cm3 of distilled water to the beaker to dissolve the solid (small volume of water) using a...

CHEM 101 Lab Exam Questions and Answers All Correct When titrating vitamin C with KIO3 (Iodate), the following steps occur (once KI and HCl are added) - Answer-1) The iodate anion reacts with I- and H+ to form I2 2) Once formed, I2 is reduced immediately by vitamin C back to I-. As each I2 reacts with one C6H8O6, each IO3- that is added results in the reaction of 3 C6H8O6 molecules 3) After all of the vitamin C in the sample has been consumed, the I2 from the addition of more iodate reacts r...
