Concept explainers
(a)
Interpretation:
The given chemical equation needs to be balanced by indicating the precipitate formed.
Concept Introduction :
In a precipitation reaction, one of the compounds formed is insoluble in water, thus, it gets precipitated out from the solution.
(a)
Answer to Problem 14A
Explanation of Solution
Aqueous (NH4)2SO4 and aqueous Ba(NO3)2 reacts to form a precipitate of BaSO4 and NH4NO3 solution.
The complete balanced equation for the reaction is:
Thus, BaSO4 is precipitate.
(b)
Interpretation:
The given chemical equation needs to be balanced by indicating the precipitate formed.
Concept Introduction :

(b)
Answer to Problem 14A
Explanation of Solution
Aqueous H2S reacts with aqueous NiSO4 to form a precipitate of NiS and H2SO4 solution.
The complete balanced equation for the reaction is:
Thus, NiS is precipitate formed in the reaction.
(c)
Interpretation:
The given chemical equation needs to be balanced by indicating the precipitate formed.
