Verified Answer :

Answer: 8.5

Explanation:

pH  is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

\(pH=-\log [H^+]\)

Given : Concentration of hydrogen ion= \([H^+]=3.16\times 10^{-9}\)

Putting in the values in the given formula:

\(pH=-log{3.16\times 10^{-9}}\)

\(pH=8.5\)

The potential of hydrogen pH of the given solution with the given concentration of hydronium ion is 8.5.

Option D) is the correct answer.

What is pH of solution?

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

pH is expressed as;

pH = -log[ H⁺ ]

Given that;

  • Hydronium ion concentration H⁺ = 3.16 × 10⁻⁹M
  • pH = ?

pH = -log[ H⁺ ]

pH = -log[ 3.16 × 10⁻⁹ ]

pH = 8.5

Therefore, the potential of hydrogen pH of the given solution with the given concentration of hydronium ion is 8.5.

Option D) is the correct answer.
