Question

Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen ions. If a substance has a pH of 6, which equation could be used to find its H value?

Answer 1

Answer:

$[H^{+} ]= 10^{-pH}$

Step-by-step explanation:

To solve this question it is important to remember logarithm rules. That is:

$a^{y} =x\\\\logx_{a} = y$

$pH = -log[H^{+}]\\\\-pH = log_{10}[H^{+} ]\\\\H^{+}] = 10^{-pH}$
