Question

What is the pH of a solution with a concentration of 2.4 × 10-5 molar H3O+? Show, or explain, the work used to solve this problem.

Answer 1

`pH=-log|H_(3)O^(+)|\\\\ pH=-log2.4*10^(-5)=-(log2.4+log10^(-5))=-(0,38-5)=-(-4.62)\\\\ pH=4.62`

Answer 2

The pH of the solution is 4.61.

Step-by-step explanation:

The pH of the solution is defined as negative logarithm of
`H_3O^+` ion concentration.

`pH=-\log[H_3O^+]`

The concentration of
`H_3O^+=2.4* 10^(-5) molar`

`pH=-\log[2.4* 10^(-5) M]=4.61`

The pH of the solution is 4.61.
