The Strength of Acids and Bases

On Thursday last week, we learned how to tell if an acid and base reaction forms an acidic, basic, or neutral salt. In addition, we discovered how tell if a solution is acidic,basic, or neutral.

First, we discussed salts. Below is a chart that shows how to know if the salt formed is acidic, basic, or neutral. As long as you know if the acid and base mixed in the reaction is strong or weak, you can determine the property of the salt.

Next, we learned about the concentrations of hydroxide and hydronium ions in solutions. To find the concentrations, we manipulate the formula below to solve for the component that we want.

You are usually given one of the concentrations and know that kw= 1.0 x 10^-14. So with those two pieces of information, you can find the solution's other concentration.

Here are a couple links that you can practice with and quiz yourself on with answers:

  1. Great post Lilly! I really liked your use of pictures in this post to emphasize the key topics. It was very helpful!

  2. To simplify the lecture from class I concluded if the acid and base were the same strength then it would be neutral salt that is produced. If the acid and base have different strengths then the substance with the strongest levels will cause the salt to be developed like the stronger of the two.
