Answer 1

(A) Water

Neutralization, the chemical reaction combining an acid with a base to produce a neutral solution, produces a salt and water.

Explanation:

Neutralization is a double displacement chemical reaction where an acid reacts with a base to form a salt and water. The reaction only products neutral compounds and is reversible in nature.

Based on Arrhenius' acid and base theory, an acid  when dissolved in water produces positive hydrogen ($H^+$) ion and negative non-metal ions. A base when dissolved in water produces positive metal ions and negative hydroxide ($OH^-$) ions. When an acid reacts with a base, the hydrogen ions react with the hydroxide ions to form water.

$H^+ + OH^-$ → $H_2O$

The metal and non-metal ions combine to form a neutral ionic compound, the salt.

Eg: Combination of Sodium Hydroxide ($NaOH$) and hydrochloric acid ($HCl$) forms Water ($H_2O$) and Common salt ($NaCl$)

Equation:

$NaOH + HCl$ ⇄ $NaCl + H_2O$

$Base + Acid$ ⇄ $Salt + Water$
