Well, once you have done it and gotten back to us, which solution is more basic?
#color(blue)("pH"_((A))) = -log["H"_3"O"^(+)] = -log(1.3 xx 10^(-3)) = color(blue)2.89#
#"pOH"_((B)) = -log["OH"^(-)] = -log(4.5 xx 10^(-8)) = 7.35#
At
#=> color(blue)("pH"_((B))) = 14 - "pOH" = color(blue)6.65#
Which solution is more basic?
