General Chemistry Interview Question:

Why all the concentration of chemical species are measured using water as solvent (for examole 1N NaOH means 40 g of NaOH in one litre of water)eventhough there are so many solvents available?

Submitted by: Administrator

Water is a neutral solvent, doesn't react with NaOH or other
chemical species.
its density nearly about 1.0.

Some reagents may be prepare in so many solvents.

for example. 0.1N perchloric acid is prepared in glacial
actic acid in non aqueous titration.

Methanolic HCl(HCl in Methanol)or Hcl in Propanol etc
