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.
