# Can water volume reduce with introduction of another chemical [duplicate]

Can a chemical be introduced to a volume of water which can actually reduce the volume of water in that container?

• Mithoron, chemistry.stackexchange.com/questions/23534/… is not a duplicate because this question is asking can Volume(solution) < Volume(solvent), i.e. there is no term for the solute volume. Sep 28, 2015 at 4:48

Density of water: $$\pu{1000 kg/m^3}$$
Density of ethanol: $$\pu{789 kg/m^3}$$
Expected density of 52 Vol.% ethanol solution: $$\pu{890 kg/m^3}$$
True density of 52 Vol.% ethanol solution: $$\pu{909 kg/m^3}$$
The volume of every ethanol-water solution is smaller than the sum of the original volumes of water and ethanol. For example if you add $$\pu{52 mL}$$ of ethanol to $$\pu{48 mL}$$ water you will get a solution with an volume of approximately $$\pu{97.9 mL}$$.
