Chapter 15: Problem 71

If a solution has a pH of 13.3, what is its hydronium ion concentration?

Short Answer

Expert verified
The hydronium ion concentration of a solution with a pH of 13.3 is \(10^{-13.3}\) M.

Step by step solution

01

Understanding the Problem

Before you start solving this exercise, understand that the pH scale is used to specify the acidity or basicity (alkalinity) of an aqueous solution. A solution with a pH of 13.3 is highly alkaline or basic, and we have to find its hydronium ion concentration [H3O+] which is calculated using the pH value.
02

Conversion of pH into concentration

The hydronium ion concentration is calculated using the inverse of the pH formula. Thus, [H3O+] = \(10^{-pH}\). So, plug the given pH value into the formula, we get [H3O+] = \(10^{-13.3}\).
03

Calculate the [H3O+] concentration

When -13.3 is input into the base of 10, we should get a very small number, which will be the hydronium ion concentration of the solution. This number represents the molarity of [H3O+] in the solution.
