Buffers work to maintain the pH of a solution by reacting with and neutralizing any strong acid or base that is added to the solution. To do this, buffer solutions must contain both a weak acid, to ...

Acids have a pH less than 7 and bases have a pH greater than 7. A pH of 7 is considered neutral. Question 1: How does the concentration of buffer components in a solution affect the change in pH when ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution ... provides a demonstration for the ...
