Determine the pH of 2.05 M (Use data from Table 16.3, as necessary.)
Step 1 of 3
Acids and Bases, advanced You can’t take quantitative analysis chemistry without having taken intro chemistry, so I’m assuming that you’ve been introduced to the concept of acids and bases and pH. You were probably taught to calculate the pH of an acidic solution as –log(acid concentration). This works just fine, until we make up a solution of 10^-8 M HCl and you are asked to calculate the pH. –log(10^-8) = 8, but a pH of 8 means that you have a basic solution. This is obviously not the case, seeing as your solution consists of water and hydrochloric acid! Where did we go wrong Water can auto-ionize, K=10^-14. As you can see from the very small K value, the auto-ionization of water has a very slight effect on pH (especially if there are other, stronger, acids and bases in solution),
