Best Answer

Because 'sdoium stearate' is the conjugate base of the weak carboxylic acid 'stearic acid'. Since a solution of stearic acid would be slightly acidic, a solution of sodium stearate will be basic or alkaline.

What is the chemical formula for Calcium Stearate?

Calcium stearate is carboxylate of calcium that is found in some lubricants and surfactants. It is a white waxy powder. It is produced by heating stearic acid, a fatty acid, and calcium oxide. It is also formed when sodium stearate is added to hard water (as scum). Sodium stearate + CaSO4 -----> C36H70CaO4 + Na2SO4 OR Sodium stearate + Ca(HCO3)2-------------> C36H70CaO4 + NaHCO3 Anyway, just wanted to refresh your memory a little bit... The formula is, as mentioned earlier : C36H70CaO4 Oh, and sodium stearate's just a fancy word for soap...
