1) CALCULATE pH of a 0.01 M SOLUTION at 25 ° C WHICH RESULTS IN THE FORMATION OF 0.01 % OH - ION IN THE REACTION OF CH3COO- WITH H2O.
CH3COO- + H2O → CH3COOH + OH -
2) FOR WHICH OF THE FOLLOWING SOLUTIONS MUST WE CONSIDER THE IONISATION OF WATER WHEN CALCULATING THE pH or pOH :
(a) 3 X 10 -8 M HNO3
(B)0.01 g H Cl in 1 L OF SOLUTION
(C)0.0080 g OF NaOH IN 0.5 L of SOLUTION
(D)1 X 10 -7 M Ca (OH)2
