PRE-DEMO DISCUSSION: Ask the students if they know what a buffer is. ... Chemically, a buffer is something that reduces/prevents the change in pH of a solution, when acid or base is added. Chemical buffers are like ... WitrynaExperiment 1: The pH of solution A is 7.0 i.e. it’s neutral. When we add 10 mL of 0.2M HCl to it, the pH decreases to 1.5. On the other hand, when we add 10 mL of 0.2M NaOH to solution A the pH shoots up to 12.5. In both these cases we see a drastic change in pH due to either the increase or decrease of proton [H ^\text {+} +] concentration.
