The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. a basic solution has a ph of 11.2. an acidic solution has a ph of 2.4. what is the approximate difference in the concentration of hydrogen ions between the two solutions? a) 1.6*10^-9 b) 4.0*10^-3 c)6.7*10^-1 d)1.6*10^-11
