Question

Find the hydrogen concentration of tomatoes if its pH is 4.5

Answer 1

Answer: hydrogen concentration = 3.16x10^-5 M

• pH of solution is the negative log of Hydrogen ion concentration in the solution

`pH=-\log _{}\lbrack H^+\rbrack`

• We will calculate the hydrogen concentration as follows :

`\begin{gathered} pH=\text{ -}\log _{}\lbrack H^+\rbrack \\ \lbrack H^+\rbrack\text{ = }10^(-pH) \\ \text{ = 10}^{-4.5\text{ }} \\ \text{ = 3.16x10}^(-5)M \end{gathered}`This means that hydrogen concentration = 3.16x10^-5 M
