Question

If the [H₃O⁺] of a solution is 1.7 x 10⁻³ M, what is the pH of the solution?

Answer 1

Answer:

The pH of the solution is 2.77

Explanation:

Data obtained from the question include:

Concentration of hydronium ion, [H₃O⁺] = 1.7 x 10⁻³ M

pH =?

The pH is define as the measure of concentration of Hydrogen ion [H⁺] or hydronium [H₃O⁺] in an acid or a base. Mathematically, it is expressed as:

pH = –Log [H₃O⁺]

With the above equation, the pH can be obtained as follow:

pH = –Log [H₃O⁺]

[H₃O⁺] = 1.7 x 10⁻³ M

pH = –Log 1.7 x 10⁻³ M

pH = 2.77

Therefore, the pH of the solution is 2.77
