calcium silicate solubility in water
Calcium silicateMEL Chemistry
Scientific description Liquid glass is basically sodium silicate Na2SiO3 and it dissolves very well in water. Ca2 from Ca (OH)2 readily replaces sodium Na to produce calcium silicate CaSiO3 which is almost completely insoluble. Normally this compound looks like a boring white powder.
