$H C l$ Hydrochloric acid

#### Explanation:

$H C l + N a O H = {H}_{2} O + N a C l$

Sodium Chloride $N a C l$ needs a chlorine atoms as well as the sodium atom from the sodium hydroxide. $N a O H$

The Hydroxide ion $O {H}^{-} 1$ needs a second Hydrogen atom to become water ${H}_{2} O$

The missing atomic ions are Hydrogen ${H}^{+} 1$ and Chorine $C {l}^{-} 1$

So the acid must $H C l$ Hydrochloric acid
