1- 0.60g of acetic acid CH3COOH is dissolved in 100 ml of water, the solution obtained (S) has a pH =2.87, Calculate the value of K, of this acid2- The solution (S: ) is obtained by adding to solution (S) 75 ml of a basic solution based on the 0.10 mol/l CH3COONA salt. Calculate the pH value of the solution (S2) 3- The solution (Sa) is obtained by adding to the solution (S) 100 ml instead of 75 ml of a basic solution based on the salt CH3COONA 0.10 mol/ L. Calculate the pH value of the solution (S;). The atomic masses are given: C =12; H=1; 0=16The solution (S: ) is obtained by adding to solution (S) 75 ml of a basic solution based on the 0.10 mol/l CH3COONA salt.
