Which property is temperature independent ?Strength of solutionMolalityMolarityNormality

The property that is temperature independent is Molality.

Here's why:

1. Strength of Solution: This is dependent on the temperature because it is the amount of solute dissolved in a solvent. The solubility of the solute can change with temperature, thus changing the strength of the solution.

2. Molality: This is defined as the number of moles of solute per kilogram of solvent. Since it's based on mass, it doesn't change with temperature.

3. Molarity: This is defined as the number of moles of solute per liter of solution. Since volume can change with temperature, molarity can also change with temperature.

4. Normality: This is similar to molarity but it also takes into account the chemical reaction that occurs. Since volume can change with temperature, normality can also change with temperature.
