Answer» Solution :No, dilute nitric acid cannot be concentrated beyond 68% by boiling. It can be concnetrated b y distilling it with concentrated sulphuric acid under reduced PRESSURE. Pure 100% nitric acid is obtained by cooling the 98% acid when COLOURLESS crystals of pure nitric acid get SEPARATED at -`42^@C`. |
