What is the melting point of distilled water. if instead of distilled water you are provided with an 5% aqueous solution of NaCl, will its melting point increase or decrease? Give reason. plz answer it |
|
Answer» Answer: The melting point of the distilled water is 0°C or 273K. On the basis of colligative properties the melting point will decrease on ADDING 5% of aqueous NaCl. Explanation: The melting point decreases because of the decreased intermolecular ATTRACTION between water molecules DUE to PRESENCE of NaCl ions. |
