Question

What is the ph of the solution when 0.2 moles of hcl is added to 1l of 1m ch3cooh?

Answer 1

CH3COOH + OH- --> CH3COO- + H2O 0.1 0.5 -0.5 mol reacts with OH. 0.5 mol from OH- reactionthe pH is equal to the pKa for acetic acid

Answer 2

Explanation:

hen 0.2 mole of HCl is added to 1 litre of a buffer solution containing 0.1 mole each of CH3COOH (Ka = 1.8 × 10–5 ) and CH3COONa.The pH of the solution is : 6
