dear xIshtar
i am wating 4 ur explanation

 

[haochen]

it is D
in exp 1 they r testing for ammonia so it is present (because ammonium break down into ammonia)
so the answer for exp 1 is re turn blue

and about exp 2 they are testing for chlorine (since the option is "bleach")
so if we add sulphuric acid nothing will happen because silver nitrate is not present.(anion table)

hope u got it
