Just enough hydrochloric acid is added from a burette to neutralise the sodium hydroxide. You can check the reaction mixture using universal indicator or a pH meter to see when it becomes pH 7.

hydrochloric acid + sodium hydroxide → sodium chloride + water. Back to top. WATCH: How to make a salt from a soluble alkali and an acid Experiment: Making a soluble salt from an alkali. Back to ...

Carbonic acid molecules are a much weaker acid than the hydrochloric acid. Therefore, the pH rises back to its original range. Figure 6. Hydrochloric acid added to a carbonic acid buffer solution. A ...

The chemical reaction that killed the manager of a Buffalo Wings restaurant in Massachusetts last week is arguably the most fundamental of all chemical reactions: Neutralization – the combination of ...

Some are bases (e.g., sodium hydroxide), others are bleach (i.e., sodium hypochlorite), and others are acids (e.g., sulfuric acid or hydrochloric acid). Not all of these chemicals play nicely together ...
