Question

H+ ion concentration in moles per litre in a solution of ph = 5.4 will be

Answer 1

Solution :

By using the formula of pH,

pH = -log [H+]

pH = -log [H+]

=> 5.4 = -log [H+]

=> -log [H+] = 5.4

Taking antilog both sides.

=> [H+] = 10^5.4

=> [H+] = 3.98 × 10^-6

Thus, H+ ion concentration in moles per litre in a solution of ph = 5.4 will be 3.98 × 10^-6 .
