Answer 1

MnSO₄ + H₂O Mn(OH)₂ + H₂SO₄

MnSO_4 + H_2O rightarrow Mn(OH)_2 + H_2SO_4 MnSO4�is a salt of strong acid and weak base. Solubility sulphuric acid in water is more than manganese hydroxide. Hence concentration of Hydronium ion will be more than hydroxide ion. As a result Manganese sulphate in water it will act as a acidic salt. RbNO_3�in water dissociates into strong base Rb(OH)_2�and strong acid HNO_3. Therefore its aquoeus�solution is neutral. NaHCO_3�is acidic in water, it disociates into Na_2CO_3�and Hydronium ion. NaHCO_3�+ H_2O rightarrow Na_2CO_3 + H_3O^+ NH_4OOCCH_3�is salt of weak base NH_4OH and weak acid CH_3COOH. In water the concentration of hydronium ion and hyfroxide ion will be nearly equal. Hence the�salt is neutral in water.

MnSO₄ is a salt of strong acid and weak base. Solubility sulphuric acid in water is more than manganese hydroxide. Hence concentration of Hydronium ion will be more than hydroxide ion. As a result Manganese sulphate in water it will act as a acidic salt.

RbNO₃ in water dissociates into strong base Rb(OH)₂ and strong acid HNO₃. Therefore its aquoeus solution is neutral.

NaHCO₃ is acidic in water, it disociates into Na₂CO₃ and Hydronium ion.

NaHCO₃ + H₂O Na₂CO₃ + H₃O⁺

MnSO_4 + H_2O rightarrow Mn(OH)_2 + H_2SO_4 MnSO4�is a salt of strong acid and weak base. Solubility sulphuric acid in water is more than manganese hydroxide. Hence concentration of Hydronium ion will be more than hydroxide ion. As a result Manganese sulphate in water it will act as a acidic salt. RbNO_3�in water dissociates into strong base Rb(OH)_2�and strong acid HNO_3. Therefore its aquoeus�solution is neutral. NaHCO_3�is acidic in water, it disociates into Na_2CO_3�and Hydronium ion. NaHCO_3�+ H_2O rightarrow Na_2CO_3 + H_3O^+ NH_4OOCCH_3�is salt of weak base NH_4OH and weak acid CH_3COOH. In water the concentration of hydronium ion and hyfroxide ion will be nearly equal. Hence the�salt is neutral in water.

NH₄OOCCH₃ is salt of weak base NH₄OH and weak acid

CH₃COOH. In water the concentration of hydronium ion and hyfroxide ion will be nearly equal. Hence the salt is neutral in water.
