Bookwork 6B #1

Postby Meagan Kimbrell 1I » Tue Nov 30, 2021 11:21 pm

6B.1) The molar concentration of HCl in hydrochloric acid is reduced to 12% of its initial value by dilution. What is the difference in the pH values of the two solutions?

Can someone please walk me through how to solve this question?

The diluted solution is 12% the strength of the original solution. In other words, the molarity of hydronium ions is 12% of the original solution. The pH scale is the -log([H3O+]). Therefore, you would calculate -log(0.12) to receive a change in pH of 0.92.
