Why do we have to add S2- slowly and gradually for precipitation to take place??
I am sorry for a wrong question..
Actually, its as follows:
Why do we add S2- slowly to Ag+ while experimenting ??
My teacher has answered it saying that if S2- is added quickly, we won't be able to study the reaction.
Its added slowly, so that we can note at what conditions does the precipitation occur.
