chemicals normally acids and bases change their chemical nature due to bacteial growth after a certain period of time for example 0.01,0.1,1m Hcl expired after 6months normaly,iron salts expecially ferros salts are converted into ferric upon oxidation(photooxidation) Fe+2 ----> Fe+3 Cu+1-----> Cu+2 most of the chemicals due to hygroscopic or anhydrous nature change by absorbing moisture from air,like NaOH and anhydrous salts e-g CaCl2
