A) \[1.0\times {{10}^{-6}}M\]
B) \[1.0525\times {{10}^{-7}}M\]
C) \[9.525\times {{10}^{-8}}M\]
D) \[1.0\times {{10}^{-8}}M\]
Correct Answer: B
Solution :
In aqueous solution of 10-8 M HCl, [H+] is based upon the concentration of H+ ion of 10-8 M HCl and concentration of H+ ion of water |
Kw of H2O = 10-14 = [H+] [OH-] |
or [H+] = 10-7 M (due to its neutral behaviour) |
So, in aqueous solution of , |
[H+] = [H+] of HCl + [H+] of water |
Hence, answer is nearer to [b]. |
