Question

At 55 degree celsius how much salt is required to make a saturated solution in 250gm of water,if the solubility of given salt is 50?​

Answer 1

Make a saturated NaCl solution by mixing an excess of salt into distilled water. The solubility of NaCl in H2O is approximately 35g/100ml at 20℃, so 100g of NaCl into 200ml of H2O should be sufficient. Transfer enough of the saturated solution into a Petri dish to cover the surface of the dish.
