Question

five solution A,B,C,D and E when tested with universal indicator showed PHvalues as 4,11,9,7 and 1 respectively
identify the solution which is
a.strongly acid
b.weakly acid​

Answer 1

Answer:

a. Solution E

b. Solution B

Explanation:

a. The pH of solution E is 1 i.e. it can almost completely dissociate with H2O to give H+ ions.

b. The pH pf solution B is 11 i.e. it can almost completely dissociate with H2O to give OH- ions.

Answer 2

E WITH pH 1 IS STRONGLY ACIDIC

D WITH pH 7 IS NEUTRAL

C WITH pH 9 IS WEAKLY BASIC

B WITH pH 11 IS MODERATELY STRONG BASE

A WITH pH 4 IS MODERATELY STRONG ACID
