Question

Equal length of magnesium ribbon are taken a two test tube is
H₂SO4 is added to test tube A&H ₂ CO3 in the test tube & B in equal amounts​

Answer 1

Answer:

a) H

2

SO

4

test tube i.e A will show more rigorous reactions

b) Since acidic strength of H

2

SO

(g)

e)

i) Since H

2

SO

4

is more acidic, it will have lower pH value.

ii) Test tube B will have lower H
