Answer» SOLUTION :Salts of strong acid and strong base : These salts do not hydrolyse and the solutionsof salts FORMED from strong acids and bases are neutral.i.e., `NaCl, NaNO_3 , KNO_3 , K_2SO_4` etc. In short ,the saltscontaining `NaCl, NaNO_3 ,KNO_3 , K_2SO_4` positive ions and `Cl^(-) , Br^(-) , NO_3^(-1) , ClO_4^(-) , SO_4^(2-)` an negative ions. Salts of WEAK acid and strong base : In this type of salts the anion of weak acid GET hydrolyse and from weak acid and solution become basic. e.g., `NaCH_3COO, K_3PO_4 , Na_2CO_3 , KHCO_3, NaOBr` etc. weak acid strong base salts solution are basic and `pH gt 7`. Salts of strong acid and weak base : In this type , the hydrolysis is occur by cation of weak base and from weak base and solution become acidic e.g., `NH_4Cl, NH_4NO_3 , CuSO_4 , FeCl_3, MgSO_4 , Ca(NO_3)_2`solutionare acidic and pH `lt` 7 . Salts of weak acid and weak base :This type of solution are almost neutral or very less acidic or basic. e.g., `CH_3COONH_4 , HCOONH_4` etc. |
