Law of definite proportions

Chemistry; General chemistry

When two pure substances react to form a compound, they do so in a definite proportion by mass. For example, when water is formed from the reaction between hydrogen and oxygen, the 'definite ...

Solubility

Chemistry; General chemistry

The solubility of a substance is its concentration in a saturated solution . Substances with solubilities much less than 1 g/100 mL of solvent are usually considered insoluble. The solubility is ...

A solution that does not change composition when distilled. For example, if a 95% (w/w) ethanol solution in water is boilled, the vapour produced also is 95% ethanol- and it is not possible to obtain ...
