Question

If 200 ml of of a 5MHCL solution is the first diluted to 1 litre and then 20 ml of this diluted solution is further diluted to 1 litre the pH of the final solution would be?​

Answer 1

Answer:

250ml/50ml = 5 times diluted So, [H+] = 1/10 /5 = 0.02 pH = -log[H+] = -log 0.02 = -0.3 + 2 = 1.7 Hence, pH of the resultant solution is 1.7.
