ABOUT HCl

Let, we have taken $ 10^{-9} $ M HCl. now, $ pH=-(log [H^{+}]).=-(log 10^{-9})=-(-9)log 10=9 $ . & We know that pH greater than 7 are base. but, HCl is acid ?? so, what is the problem ??

Remember that in an aquas solution you already have $[H^+]=10^{-7}$. You can't make it less than that. :P
