Pure Substances Concentration

[Funmi Baruwa]

In Monday’s lecture Dr. Lavelle said that sold and kiwis don’t have concentration. So then in the example he gave, why did he count the products that were in the aqueous phase?

Thank you in advance :) -

I think the pure substance he mentioned is solid (like metals) and liquid (like water, for example). Aqueous is often counting into the concentration since it is not "pure" I guess, if this helps.

Aqueous substances are not considered pure substances, rather they are solutes that participate in the reaction and must be included in the equilibrium calculations.

[Anirudh Mahadev 1G]

Aqueous substances are simply dissolved in water, they do not make up liquid as a pure substance. For example, hydrochloric acid is not often 100% HCl, it is normally a small percentage of the total volume, such as 5% HCl.

The aqueous substances have significant and measurable changes in concentration, whereas the solvent water is present in such a high amount that the change is negligible.
