What combinations of acid and base can be used to make the salt sodium chloride?

To make sodium chloride (NaCl), you need to combine hydrochloric acid (HCl) and sodium hydroxide (NaOH).

The chemical reaction that takes place is:

```

HCl + NaOH → NaCl + H2O

```

This reaction is a neutralization reaction, which means that the acid and base react to form a salt and water.

Other combinations of acid and base that can be used to make sodium chloride include:

* Hydrochloric acid and sodium carbonate (Na2CO3)

* Hydrochloric acid and sodium bicarbonate (NaHCO3)

* Hydrochloric acid and sodium acetate (NaC2H3O2)

These reactions all produce sodium chloride and water.
