Question

A 100 liter solution contains 0.50 M acetic acid and 0.38 M potassium acetate If 25.0 mL of water are added to this system, indicate whether the following statements are true or false. (Note the the volume MUST CHANGE upon the addition of water) A. The concentration of CH COOH will decrease. B. The concentration of CH Coo will increase C. The equilibrium concentration of H,0 will decrease ? D. The pH will increase. E. The ratio of [CH COOH/ICH CO0'] will decrease Submit Answer Ratry Entire Group 9 more group attumpts romaining SAMSUNG 5

Explanation / Answer

1. True, Concentration of acetic acid decreases on Dilution, since disassociation of acetic acid increase on Dilution which decreases the concentration of acetic acid

2. True, since disassociation of acetic acid increases the concentration of acetate

3. False, since concentration of H3O+ increases

4. False, since H3O+ increased, pH decreases

5. True, as acetate concentration increases, ratio decreases
