NH3 is basic in nature but only in its aqueous form- When NH3 reacts with water- NH4OH is formed which is a base and contains NH-4 and OH-x2212- ions- Hence- the red litmus turns blue-

$N H_{3}$ is basic in nature but only in its aqueous form. When $N H_{3}$ reacts with water, $N H_{4} O H$ is formed which is a base and contains $N H_{4}^{+}$ and $O H^{-}$ ions. Hence, the red litmus turns blue.
