Melting point of ice made from distilled water is 0�C.
Melting point of any impure liquid is more than pure (original) liquid. Hence, if the ice is made from sea water (which has impurities) it's melting point will be more.

Melting Point of Ice from Distilled Water
The melting point of ice formed from distilled water is 0°C (32°F) under standard atmospheric pressure. This is the temperature at which solid ice transitions to liquid water.
Effect of Sea Water on Melting Point
When ice is made from sea water, the melting point is affected due to the presence of dissolved salts. Here’s how:
Decrease in Melting Point
- Freezing Point Depression: Sea water contains salt (mainly sodium chloride) and other minerals, which disrupt the formation of ice crystals.
- Colligative Properties: The presence of solutes (like salt) lowers the freezing point of the solution. This phenomenon is known as freezing point depression.
- Practical Implications: As a result, ice made from sea water will melt at a temperature lower than 0°C, often around -2°C to -3°C, depending on the concentration of salt.
Key Factors Influencing Melting Point
- Salt Concentration: Higher salt concentrations result in a greater decrease in the melting point.
- Temperature and Pressure: Changes in external conditions can also influence melting points, but the primary factor in this case is the dissolved salt.
In summary, the melting point of ice made from distilled water is 0°C, while the melting point of ice from sea water is lower due to the presence of salts that cause freezing point depression.
