studiot Posted June 10, 2021 Posted June 10, 2021 Do try to do the short question I asked at the end about common salt. It is meant to help develop your understanding.

studiot Posted June 10, 2021 Posted June 10, 2021 3 minutes ago, NotYou said: How can water be diluted? A solution is a mixture of two or more substances. Just to consider two, A and B - alcohol and water or salt and water. The mixture contains a certain % of A and (100 - %A) of B Adding (pure) A or B to the mixture will increase the concentration of A or B, decreasing or diluting the concentration of the other. In other words diluting is the opposite of concentrating. I know in common parlance we often use diluting to mean to add water. This is not untrue just only part of the full (scientific) story.

From what you have said before, I would think the final objective might be to help you understand the following presentation about dilution and pH calculation in swimming pools. https://courses.lumenlearning.com/cheminter/chapter/calculating-ph-of-salt-solutions/
