Is normality temperature dependent?

Yes, normality is temperature dependent. Temperature can affect the solubility of solutes. For instance, if a solute dissolves more or less readily at different temperatures, this can change the concentration of the solution, and thus the normality if the concentration changes. Temperature changes can also cause the volume of a solution to expand or contract. Since normality is defined as the number of equivalents of solute per liter of solution, any change in volume due to temperature will inversely affect the concentration.
