your teacher is going to come here ... and he/she is going to see every homework question on Yahoo! Answers and you are going to fail or get kicked out for cheating .... and i'm going to be there laughing about how pathetic it is.

hello there, yet again crucial formula [H+][OH-]=1.0x10^-14
you have [H3O+]=3.98x10^-13
[OH-]= 1.0x10^-14/[H3O+], and your concentration for limewater is 10^-13, so it would be basic. pH=-log[3.98x10^-13]
