For this problem, we are being asked to calculate the pH of KCl solution
In this case, we have an ionic salt. Recall that ionic salts are made up of positively charged ion (cation) and a negatively charged ion (anion).
To determine if the ionic salt would be acidic, basic, or neutral, we need to identify the acidity or basicity of the cation and anion.
▪ charge of +2 or higher→acidic
▪ less than +2 → neutral solution
What is the pH of a 0.10 M solution of KCl?
