Question

What is the
Effect of temperature on molarity,molality and normality?

Answer 1

Answer:

Molarity is dependent on temperature, whereas molality is not. With temperature, molarity varies. Molarity is solute moles per litre of solution. As the temperature increases, water expands, so the solution's volume therefore increases.

Answer 2

Answer:

Molarity is dependent on temperature, whereas molality is not. With temperature, molarity varies. Molarity is solute moles per litre of solution. As the temperature increases, water expands, so the solution's volume therefore increases.

So with change in temperature, molarity also changes. But there is no effect of temperature on molality. For example, with increase in temperature, volume will increase and then molarity will decreases
