 What change will be caused by the addition of a small amount of HCl to a solution containing acetate ions and acetic acid? 

1-The concentration of acetate ions will decrease and the concentration of acetic acid will increase. The concentration of acetic acid will decrease and the concentration of acetate ions will increase 

2- The concentration of acetate ions will increase as will the concentration of hydronium ions. 

3- The concentration of hydronium ions will increase significantly. 

T4- the acetate ions will precipitate out of the solution as its acid salt.
