|
Answer» Solution :`Mg(OH)_(2)` is a diacidic base and `H_(2)SO_(3)` is a dibasic ACID. HENCE there is possibility of three different salts. `Mg(OH)_(2) + H_(2)SO_(3) rarr underset("MAGNESIUM hydroxy bisulphite")(Mg(OH)HSO_(3) + H_(2)O)` `Mg(OH)HSO_(3) + H_(2)SO_(3) rarr underset("Magnesium bisulphite")(Mg(HSO_(3))_(2) + H_(2)O)` `Mg(OH)_(2) + H_(2)SO_(3) rarr underset("Magnesium bisulphite")(Mg(HSO_(3))_(2) + H_(2)O)` `Mg(HSO_(3))_(2) + Mg(OH)_(2) rarr underset("Magnesium sulphite")(2MgSO_(3) + 2H_(2)O)` |
