pH Buffer Solution

We have four containers with universal indicator: Two of them are mixed with distilled water, the other two mixed with a buffer solution of ammonia and vinegar. We compare the pH changes when we add dropper-fulls of 1M NaOH and HCl to the dishes. We see that the water changes pH very easily, while the buffer solution is much more resistant.

Always wear proper PPE when working with chemicals!
