4. Tristearin and stearic acid are insoluble in water. However, sodium stearate (soap) is soluble. Why is there this difference in solubility? 5. Use of concentrated NaOH (lye or caustic soda) in soap preparations can produce a very basic product. A good soap tests between pH 7 and 9; pH 10 is rather harsh; a pH of 11 means something is wrong. How does your soap compare with these values? How...
