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
