In the organic chem, we prepared soap by using tallow and sodium hydroxide. After keep checking the regular 6 weeks of PH, my ph did not get to 7 scale but remained till 10. my question is what could be the error possible i made there that did not let my soaps to be more neutral? there was no gylcerol made on soap layers. also, my yield came out to be 133.33%. I don't know yield relation to PH scale for soaps.
