Ammonium acetate which is 0.01 M , is hydrolysed to 0.001 M concentration. Calculate the change in pH in 0.001 M solution, if initially pH = pK _ a

Step-by-step solution

array c CH ₃ COONH ₄+ H ₂ O CH ₃ COOH + NH ₄ OH 0.01 M & 0.001 M pH = p K_ a + [ CH ₃ COONH ₄ ] [ CH ₃ COOH ] = p K_ a + [ 0.01 0.001 ] = p K_ a + 10 = p K_ a +1 Change in pH =1 array
