Answer» D is neutral, as its pH value is equal to 7 b) C is strongly alkaline, as its pH value is 11. c) B is strongly acidic, as its pH value is equal to 1 d) A is WEAKLY acidic, as its pH value is equal to 4 and more than solution B. e) E is weakly alkaline, as its pH value is equal to 9 and less than C. pH value of the given solution in increasing order of hydrogen-ion concentration: 11<9<7<4<1 |
