Data and Conclusions Equilibrium Part A: The equilibrium and dissociation of HC2H3O2 in Water Q1. Write the chemical equation for the dissociation of HC2H3O2 in water Prediction: Which way is the equilibrium going to shift when you add NaC2H3O2 LEFT RIGHT NO SHIFT (circle one) A3. Color of original equilibrium mixture: ________________________________ Q2. Based on the initial color of the mixture, is the H3O+ concentration relatively high or relatively low? Briefly explain how you arrived at your answer. A4. Describe the color change after addition of NaC2H3O2 Q3. Was your prediction above correct? Yes No Briefly explain using Le Chatelier's principle and your observations. Example: (Use this template sentence throughout the experiment) After adding / removing __________________ , the equilibrium shifts to the _____________. This is confirmed by _________________________________ ________________________________________________________________ (describe the observation you made). Q4. What happened to the concentration of the reactants when you added NaC2H3O2? (circle one) INCREASE DECREASE STAYED THE SAME
