1- The Composition of the Sodium silicate solution is Na2O: 10%, SiO2: 27%, H2O: 63% and the Density 1.39 g/ml. the Composition of the Sodium hydroxide is NaOH Solid and the density is 2.13 g/ml.
2- The SiO2 was from Na2SiO3 solution while the Na2O was from both Na2SiO3 solution and NaOH solid.
3- The sodium silicate as purchased had a SiO2/Na2O Module of 2.58 and the solute concentration of 37% (by mass).
