Question

assertion: ice containing dissolved sugar will melt at high temp then pure ice
reason: dissolving sugar in water lead to depression in freezing point

Answer 1

ice with sugar solution

Answer 2

Assertion is false while statement for reason is correct

Explanation:

• Water freezes at 32 degrees Fahrenheit (0 degrees Celsius), but a change in freezing point is observed when any solute (eg: sugar) is added .
• The sugar molecules basically prevent the water molecules from forming hydrogen bonds, which are needed for conversion into ice. This is referred to as depression in freezing point .
• Therefore , considering this , assertion statement is false which says that ice containing sugar will melt at higher temperature than pure ice. It should melt at lower temperatures than pure ice.
• However , reason statement is correct which says dissolving sugar lowers the freezing point of water.
