p^H = - log₁₀ [H+]. The p^H of a solution containing hydrogen ion concentration of

0.001M solution is _____ ( 3 / 11 / 14)

3

We are given that the hydrogen ion concentration [H⁺] is 0.001M

We know that : -

p^H = - log₁₀ [H+]

⇒ p^H = - log₁₀[0.001]

⇒ p^H = - log₁₀[10^-3]

⇒ p^H = -(-3) log₁₀[10]

(As log₁₀[10] = 1)

⇒ p^H = 3 × 1

⇒ p^H = 3
