How To Make Sodium Silicate At Home - DIY Waterglass

We make some Sodium Silicate (Na2SiO3), also called Sodium Metasilicate or Water Glass, by reacting Sodium Hydroxide (NaOH) from common drain cleaner with Silica Gel (SiO2) obtained from cat litter. The simplified equation is below: 2NaOH + SiO2 → Na2SiO3 + H2O Reactants used: NaOH - 60g SiO2 - 45g H2O - 75mL Comment, Like and Subscribe!!!
