PRODUCT PROPERTIES: Soda Ash is a moderately strong alkali having pH 11.1 in a 0.2% solution in water at 20 degree centigrade compared to Sodium Bicarbonate (Bicarb) at pH of 8.4. Soda Ash is readily soluble in water in the finished form. Soda Ash is granular in appearance and is a free flowing powder. Soda Ash solutions have no appreciable corrosive effect on mild steel and cast iron. Aluminium and Galvanized steel are, however, susceptible to attack, especially at higher temperature. Light Ash and Dense Ash are chemically identical, the only difference being in their bulk densities, the later being higher. Both grades conform to Pakistan Standard Specification PS:10 of 1979. Typical analyses of Soda Ash are as follows:
