[0010001111]... Hello User... [1001010101]
Here's your answer...

When using a universal indicator, a pH of 7 is considered neutral. Any value less than 7 is acidic and any value more than 7 is basic. How close the value is to 7 determines how strong or weak it is.
A = 4
B = 1
C = 11
D = 7
E = 9

D is definitely neutral.
A and B are acidic.
C and E are alkaline.
Since A's value is closer to 7, it is weakly acidic. B will be strongly acidic.
Since E's value is closer to 7, it is weakly alkaline. C is strongly alkaline.
