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.
Sodium Stearate , or Sodium Palmate. The formulas are Sodium stearate CH3(CH2)16COO^-Na^+ Sodium, palmate CH3(CH2)13COO^-Na^+ Soaps that lather (dissolve) in salt water have the sodium ion replace by a potassium ion (K^+). This is because of the common ion effect of sodium in sodium stereate and sadium in sodium chloride of salt water.
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.
