Here is the answer :-
A 1-- This is because common salt reduces the solubility of soap in solution due to which it seperates out as solid precipitate , which can be use. If Nacl is not added soap remain in solution only.
A 2-- If we add soap solution in oil it will then form another layer of oil, means it will not dissolve .
If we add soap to hard water ,
No lather will formed only .
If we add soap solution in soft water ,lot of lather will formed along with foam.
A3-- Yes we can use KOH instead of NAOH in soap formation. Only difference is that with KOH you will get liquid soap
B-- "This question is tricky"
Ethanol is an alcohol and alchohol doesn't show acidic character because they doesn't release H+ ions . They are neutral . so answer will be , There is no any acidic character shown by Ethanol.
That's all . Hope u get your answer.Thanks for reffering me.
