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.
\(pH=-log|H_{3}O^{+}|\\\\ pH=-log2.4*10^{-5}=-(log2.4+log10^{-5})=-(0,38-5)=-(-4.62)\\\\ pH=4.62\)
Answer:
The pH of the solution is 4.61.
Explanation:
The pH of the solution is defined as negative logarithm of \(H_3O^+\) ion concentration.
\(pH=-\log[H_3O^+]\)
The concentration of \(H_3O^+=2.4\times 10^{-5} molar\)
\(pH=-\log[2.4\times 10^{-5} M]=4.61\)
The pH of the solution is 4.61.
