Question

_____ gas dissolved in water to form an alkaline solution.$(N{H}_3/H_{2}S{O}_4/HCl)$

Answer 1

• NH₃ gas dissolved in water to form an alkaline solution.
• NH₃ forms NH₄⁺ ions by accepting a hydrogen ion, whereas both H₂SO₄ and HCl release H⁺ in a solution. when NH₃ reacts with water the reaction involved can be shown as:
  ${\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)+{\mathrm{NH}}_3\left(\mathrm{g}\right)\to \mathrm{N}{{\mathrm{H}}_4}^{+}\left(\mathrm{aq}\right)+{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)$
  It is visible that OH^-(hydroxide ions) are released as a product that makes the solution alkaline.
