The answer is (3) pH 3 to pH 1. The pH is related to the concentration of H3O+ with the relationship: pH = -lg c(H+). So when concentration of H3O+ increase, the pH will decrease. And decrease 2 when when increase hundredfold. Because 100=10^2.
Basically a covalent bond would have been made based on two atoms so that it can collaboratively set a trace of more electrons. Although there is no atom that is zero which if it had that then it would considerably be a net charge which it is not from this problem. What makes it unique about it is that this attractive force from creating the bond of the electrons that would be purposely activated that are the nuci for constructive used into two atoms.
