PLEASE HELP <br> What is the pH of a weak acid solution that has an [H+] of 2.1 × 10^–6 M

sveticcg [70]

Answer:

pH ( potential Hydrogen ) is a negative logarithm of molar concentration of hydrogen ions.

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

therefore:

$pH = - log(2.1 \times {10}^{ - 6} ) \\ { \boxed{pH = 5.68}}$
