Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Part A
We define the activity of pure liquids as 1 to define the standard state. However, this is
an arbitrary choice. Find the equilibrium constant, K, for the autoprotolysis of pure
water at 25° C using the molarity standard state for water (i.e. defining the activity as
1 for a water concentration of 1 mol/l). You may take the density of water to be 1.0
g/ml.
