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.
