Chemical properties of metal |
| Answer» 1) Most of the metals form respective metal oxides when react with oxygen.Metal + Oxygen → Metal oxide2) Metals form respective metal hydroxide and hydrogen gas when react with water.Metal + Water → Metal hydroxide + Hydrogen3) Metals form respective salts when react with dilute acid.Metal + dil. acid → Metal salt + Hydrogen4) Most of the metal oxides are insoluble in water. Alkali metal oxides are soluble in water. Alkali metal oxides give strong base when dissolved in water. | |
