Question

11.
If 10 mL of H2SO4 is mixed with 10 mL of Mg OH)2 of the same
concentration, the resultant solution will give the following colour with
universal indicator :
(A) Red
(B) Yellow
Green
(D) Blue​

Answer 1

hope..it....helps.........

Answer 2

The solution will give Green colour with universal indicator. Thus, option (c) is the correct option.

• Universal indicator is used to determine pH of a solution.

• According to the question,

the volume of H2SO4 = the volume of Mg(OH)2

also we know that both are strong acid and strong base respectively with  

acidity = basicity = 2

• Then on mixing, they will result into a neutral salt with pH = 7 indicating green colour on universal indicator.
