Calculate the pH of a solution of {eq}5.0 \times 10^{-4} {/eq} M HCl.
Question:
Calculate the pH of a solution of {eq}5.0 \times 10^{-4} {/eq} M HCl.
Calculating pH:
The concentrations of acids and bases are wide-ranging and that presents a challenge when investigating the degree of acidity or alkalinity. For example, concentrations of ( {eq}\rm 10^{-14} M\ \text{and}\ 10^{-13} M {/eq} for say {eq}\rm H^+ {/eq} ) have a magnitude of 10 times apart and yet the degrees of acidity or alkalinity are more comparable qualitatively than a 10-time difference in concentration would hint. The pH scale gives a more intuitive measure of the degree of acidity of a solution.
