The pH of a solution with a concentration of hydronium ions of 5.29×10⁻¹⁰ is 9.28 ,therefore option (d) is correct.
pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution.
The pH scale usually ranges from 0 to 14. Aqueous solutions with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 is neutral.
To calculate the pH of a solution with concentration of hydronium ions of 5.29×10⁻¹⁰-
We know that ,
pH=−log(H₃O⁺) ..............(1)
Given, H₃O⁺=5.29×10⁻¹⁰
So, we need to calculate,
= −log(5.29 .10⁻¹⁰) ............from above (1)
= 9.28
The pH of a solution with a concentration of hydronium ions of 5.29×10⁻¹⁰ is 9.28 ,hence option (d) is correct.
