Question

What is the pH of a 0.1M acid solution?

A. 1
B. 0
C. -1

Answer 1

Hello!

We have the following data:

[H+] = 0.1 M →
`1*10^(-1)`

Formula:

`pH = - log\:[H^+]`

`pH = - log\:[1*10^(-1)]`

`pH = 1 - log\:1`

`pH = 1 - 0`

`\boxed{\boxed{pH = 1}}\end{array}}\qquad\checkmark`

Answer:

A. 1
