Question

Calculate the concentration of H3O + ions in a solution of NaoH whose concentration is 0.62M at 25 ° C.

Answer 1

The pH of this solution is 0.207

Hello

To solve this question, we need to use the formula of solving pH of a solution from hydrogen or hydronium ion.

`\begin{gathered} pH=-\text{log\lbrack{}H}_3O^+\rbrack \\ \end{gathered}`

Now, we would proceed to substitute the given value and solve for it.

`\begin{gathered} pH=-\log \lbrack0.62\rbrack \\ pH=0.207 \end{gathered}`

NB: we did not use the value of temperature because it is not needed in this solution.

From the calculation above, the pH of this solution is 0.207
