. Five solutions A,B,C,D and E when tested with universal indicator showed pH as
4,1,11,7 and 9, respectively. Which solution is
(a) neutral?
(b) strongly alkaline?
(c) strongly acidic?
(d) weakly acidic?
(e) weakly alkaline?
Arrange the pH in increasing order of hydrogen-ion concentration.

Solution D is neutral
solution C is strongly alkali.
solution B is strongly acidic.
solution A is weakly acid.
solution E is weakly alkali metals.
C <E <D <A <B= increasing order.

hope it helps you !!! :)

Ph given 
a=4,b=1c=11,d=7 ,e =9
 dis the neutral
c is the stronger alkaline sol
b is strongly acidic
a is weakly acidic
e is weakely alkaline
increasing order
c,<e<d<a<b
