What is the pH of a 0.00125 M HCl solution?

timofeeve [1]

Answer:

$pH=2.9$

Explanation:

Hello,

In this case, the pH is computed by:

$pH=-log([H^+])$

Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:

$pH=-log(0.00125)\\\\pH=2.9$

Regards.
