How To Preserve Sodium Hydroxide


Also note that glass bottles that store sodium hydroxide solution cannot use glass stoppers, because the composition of ordinary glass contains more silica, sodium hydroxide can react with silica: 2NaOH+SiO2=Na2SiO3+H2OWhen the water evaporates Later, Na2SiO3 (sodium silicate) can make the glass bottle and the stopper adhere firmly, so the reagent bottle containing the sodium hydroxide solution in the laboratory uses a rubber stopper or a cork stopper.
