Which is not a property of water ?

Options

A. It is a colourless and tasteless liquid.
B. There is no hydrogen bonding in solid state of water.
C. It is an excellent solvent for transportation of ions in plants and animals.
D. Ice is lighter than liquid water.

Explanation

To determine which option is not a property of water, we can analyze the given statements one by one:

1. **Colorless and Tasteless Liquid**:
- Water is indeed colorless and tasteless. This statement is true.

2. **No Hydrogen Bonding in Solid State of Water**:
- This statement is false. In the solid state (ice), water molecules form extensive hydrogen bonds, which is why ice has a lower density than liquid water. Therefore, this statement is incorrect.

3. **Excellent Solvent for Transportation of Ions in Plants**:
- Water is known as the "universal solvent" because it can dissolve many substances, including ions. This statement is true.

4. **Ice is Lighter than Hot Liquid Water**:
- This statement is also false. Ice is less dense than liquid water, which is why it floats. However, the comparison made here is not accurate as it suggests that hot water is lighter than ice, which is misleading. The maximum density of water occurs at 4 degrees Celsius, and ice is indeed lighter than liquid water at this temperature.

Based on this analysis, the statement that is not a property of water is the second one: "No hydrogen bonding in solid state of water."

**Final Answer**: The incorrect property of water is: "No hydrogen bonding in solid state of water."
