Adding a strong base to a solution of acetic acid would result in a neutralization reaction. Acetic acid is a weak acid, and it will react with the strong base to form water and an acetate salt. The strong base will provide hydroxide ions OH- that will react with the hydrogen ions H+ from the acetic acid, decreasing the concentration of hydrogen ions in the solution.The reaction can be represented as follows:CH3COOH acetic acid + OH- from strong base CH3COO- acetate ion + H2O water As the reaction proceeds, the concentration of acetic acid will decrease, while the concentration of acetate ions will increase. The equilibrium will shift to the right to compensate for the decrease in hydrogen ions, which will result in the formation of more acetate ions and water.The overall effect of adding a strong base to a solution of acetic acid is a decrease in the concentration of hydrogen ions and an increase in the concentration of acetate ions. This will cause the pH of the solution to increase, making it less acidic and more basic.
