Question

Assume that there is a puddle that contains 12.0 kg of water and it froze outside since it is -1°C. The

Answer 1

The temperature that must be to freeze the solution would be -21.1 ° C.

How to calculate the freezing temperature of this solution?

To calculate the freezing temperature we must take into account the following information.

• Solution with a salt concentration of 10% is frozen at -6°C
• Solution with a salt concentration of 20% is frozen at -16°C
• Solution with a higher concentration is frozen at -21.1°C

According to the above, it can be inferred that the puddle has a 50% concentration of salt because they had 12 kg of water and 6 kg of salt.

So the lowest freezing temperature would be 21.1°C because the puddle is 50% concentrated.

Note: This question is incomplete because there is some missing information. Here is the missing information:

• A 10% salt solution freezes at about 20°F (-6°C), and a 20% solution freezes at 2°F (-16°C).
• The lowest freezing point obtainable for salt solutions is −21.1 °C
