Question No. 137
How many hydrogen ions are present in 1 ml of a solution of pH = 13?
(A) 6.02 x 1013
(B) 6.02 x 1012
(C) 6.02 x 107
(D) 6.02 x 105​

Answer 1

Answer:

C) 6.023 x 10⁷

Explanation:

pH  = 13

[H⁺] = $10^{\text{-pH}}$

[H⁺] = $10^{-13}$

$10^{-13}$ M Hydrogen

So  $10^{-13}$ x 6.023 x 10²³ ions per liter

So 10⁻¹⁶ x 6.023 x 10²³ Hydrogen Ions per mL (1L = 1000mL)

So 6.023 x 10⁷
