In chemistry, the concentration of a solution refers to the amount of substance dissolved in a certain volume of the solution. The volume chosen is 1 dm3 1. Water flux will increase linearly with applied pressure, as seen in Eqn (6.33). Increasing concentration in the feed will on the other hand lower the water flux, when the mercuric ion concentration is increased from 0.000001 to 0.00001. The chemical formula for the reaction is,Since this is a. The rate of reaction will increase as the hydrogen peroxide concentration increases.
