i don't have a clue!
2Na+ C18H35O2- (solute) +Mg++ = Mg(C18H35O2)2 (precipitate) + 2Na+
i googled it and i think its C24H44O6Na http://64.233.169.104/search?q=cache:DwU2BouFCLYJ:www.sciencelab.com/xMSDS-Sodium_Stearoyl_Lactylate-9925041+formula+for+sodium+stearoyl+lactylate&hl=en&ct=clnk&cd=6&gl=us&client=firefox-a
In hard water we find Calcium and Magnesium ions. These react with the Sodium stearate (soap) to form Calcium and magnesium stearate and Na+ ions Sodium stearate+ Ca2+ +Mg2+ --> Calcium stearate + Magnesium stearate + Na+ ions
sodium sterate, an organic compound apparently present in soap??
sodium acetateThe chemical name for NaC2H3O2 is sodium acetate.
because it then lets the deodorant stick to your body. Without it, the deodorant would just roll off your body like water. The side of sodium stearate which sticks to oils, stick onto your skin whilst the other side holds on to the deodorant itself.

what is difference beetwin sodium stearate and potassium stearate
Sodium chloride is soluble in water, calcium stearate not.Put the mixture in water, stir and filter; sodium chloride remain in solution, calcium stearate on the filter.

2Na+ C18H35O2- (solute) +Mg++ = Mg(C18H35O2)2 (precipitate) + 2Na+
sodium stearate C17H35COONa , sodium palmitae C15H31COONa
C17H35COONa
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.

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...
It is also known as a surfactant
