Question

the pH of a solution of HCL is 4 this shows that the molarity of the solution is
4.0M
0.4M
0.0001 M
0.001 M​

Answer 1

Answer:0.0001M

Explanation:pH=-log(H+)

4=-log(H+)

(H+)=10^(-4)

(H+)=0.0001

Hope it will help you.....

Answer 2

Correct Option:- c) 0.0001 .

Given,

pH = 4

we have know that,

pH = -log[H+]

=> log [H+] base(10) = -4

=> [H+] = Anti log[-4] base (10)

=> [H+] = 10^-4 .

In this solution,

concentration of H+ = concentration of HCl

So, Molarity of the solution is 0.0001M .

Hope it's helpful to you.
