I will generally use around 2oz of material per every 16fl.oz. Oil Chemists' Soc.,30, 288–291 (1953). Each sodium soap has a large range of temperature between fair and high solubility, whereas the potassium soaps go abruptly into solution, at almost the same temperature and concentration of each soap. Hydrolysis obscures the temperatures of solution but is obviated by the presence of a small excess of alkali. Emulsification Test for Lipid. _____ During washing oily dishes, it is not enough to just use water. Google Scholar. Ramalingam, K., Ph.D. thesis, Osmania University, Hyderabad, India (July 1955).
