Which of the following statements is incorrect ?

Options

A. The freezing point of water is depressed by the addition of glucose
B. The degree of dissociation of a weak electrolyte decreases as its concentration decreases
C. Energy is released when a substance dissolves in water provided that the hydration energy of the substance is more than its lattice energy
D. If two liquids that form an ideal solution are mixed, the change in entropy is positive

Explanation

To determine which of the statements is incorrect, let's analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** The freezing point of water is depressed by the addition of glucose.

**Explanation:** This statement is based on the colligative property known as freezing point depression. When a non-volatile solute, such as glucose, is added to a solvent (water), the freezing point of the solvent decreases. This is a well-established principle in chemistry.

**Conclusion:** This statement is **correct**.
