The pH of 0.1 M solution of the following salts increases in the order |
|
Answer» `NaCl gt NH_(4)Cl LT NaCN lt HCL` NaCl neutral solution `NH_(4)Cl` slightly acidic due to the reaction `NH_(4)^(+) + H_(2)O HARR NH_(4)OH + H^(+)` NaCN slightly alkaline due to the reaction `CN^(-) + H_(2)O hArr HCN + OH^(-)` HCl highly acidic The pH of the solution will follow the order highly acidic `lt` slightly acidic `lt` neutral `lt`slightly alkaline i.e., `HCllt NH_(4)Cl lt NaCl lt NaCN`. |
