Question

If 10 ml of H2 S o4 is mixed with 10 ml of MG 42 of the same concentration the resultant solution will give the following colour with universal indicator

Answer 1

Answer:

Answer-

(C) green

Explanation:

Sulphuric acid is a strong acid and magnesium hydroxide is a strong base,

so naturalisation reaction takes place and metal salt and water is produced.(neutral)

Please mark me brainliest!

Answer 2

The resultant solution will give the following colour with universal indicator :

Green

First of all, we see that the concentration of both the acid and the base are the same and the acid is dibasic and the base is diacidic. So, complete neutralisation occurs and the salt produced is neutral.

The reaction is shown below.

H₂SO₄ + Mg(OH)₂ → MgSO₄ + 2H₂O

Due to the complete neutralisation the salt formed would neither be acidic nor basic.

As a result, if we introduce an universal indicator to the resulted neutral solution, the colour obtained would be green.
