WebBuffers, solutions that can resist changes in pH, are key to maintaining stable H ^+ + ion concentrations in biological systems. When there are too many H ^+ + ions, a buffer will absorb some of them, bringing pH back up; … WebExperiment 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.
