Question

equal volume of each 10% HCL and 10% analysis next comment on the nature of resulting solution​

Answer 1

Given volume of acid (HCl) is 50 ml and concentration is 0.4 N

Volume of base (NaoH) is 50ml and concentration is 0.2 N .

Actually it is simple reaction in which salt is formed then some acid is remains find pH of that acid .

Base is 0.2 * 50Nml = 10Nml

Acid is 0.4*50Nml = 20Nml.

So remaining acid is 20–10 = 10Nml in 100ml of solution. So concentration of acid is 10/100N = 0.1N

So pH is -log[H+]

pH = -log(0.1)

= 1.

Therefore pH of solution is 1
