Question

Calculate the [H+] given a pH of 2.80

Answer 1

The [H+] is 1.6x10^-3 M.

Step-by-step explanation:

1st) We can calculate the concentration of H+, using the pH formula:

`\begin{gathered} pH=-log\lbrack H^+\rbrack \\ 2.80=-log\lbrack H^+\rbrack \\ 10^((-2.80))=\lbrack H^+\rbrack \\ 1.6*10^(-3)M=\lbrack H^+\rbrack \end{gathered}`

So, the [H+] is 1.6x10^-3 M.
