Question

Base.

Hint:

Acid-base reactions always produce salt and water. Acids reacting with metals or carbonates can also produce hydrogen gas or carbon dioxide.

Answer 1

When an acid reacts with a base, a salt and water are produced in a neutralization reaction. For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), sodium chloride (NaCl) and water (H₂O) are formed. The chemical equation is: \[ HCl (aq) + NaOH (aq) \rightarrow NaCl (aq) + H_2O (l) \]
