Question

The concentration of Hydrogen ion in a sample of soft drink is 4.0 x 10-3 M. What is its plH ?​

Answer 1

Answer:

The pH of the given soft drink is 2.4

Explanation:

Given that,

concentration of  H⁺ ion = 4×10⁻³ M

the relation pH of the solution and the molar concentration of  H⁺ ions is given by,

      pH = - log [H⁺]

⇒         = - log( 4×10⁻³ )

⇒         = - log(4) +- log(10⁻³ )

⇒         = - 0.6 + 3

⇒         =  2.4

Hence, the pH of the soft drink is 2.4 and it is acidic.
