Solutions can also be gases dissolved in liquids, such as carbonated water. There can also be gases in other gases and liquids in liquids. If you mix things up and they stay at an even distribution, it is a solution. You probably won't find people making solid-solid solutions.
As a salt of a strong acid (H 2 SO 4) and weak base (NH 3 ), its solution is acidic; pH of 0.1 M solution is 5.5. In aqueous solution the reactions are those of NH 4+ and SO 4−2 ions. For example, addition of barium chloride, precipitates out barium sulfate. The filtrate on evaporation yields ammonium chloride .

Sep 11, 2019 · In a chemical equation, the symbol (aq) follows a species name to indicate that it is in aqueous solution. For example, dissolving salt in water has the chemical reaction: NaCl (s) → Na + (aq) + Cl - (aq) Although water is often called the universal solvent, it dissolves only substances that are hydrophilic in nature.
