Question

An excess of aqueous silver nitrate is added to aqueous barium chloride and
precipitate is removed by filtration. What are the main ions in the filtrate?
(a) Ag+and NO3- only
(b) Ag+ and Ba+2 and NO3-
(c) Ba+2 and NO3- only
(d) Ba+2 and NO3- and Cl-​

Answer 1

Explanation:

see the reaction,after the reaction AgCl is precipitated out (it means it is now insoluble) the only compound left is barium nitrate which is an ionic compound so it will dissociate

Answer 2

Answer:

Precipitation reaction which is defined as the "formation of an insoluble salt". Precipitates are the insoluble salts produced during precipitation processes. Precipitation reactions are often double displacement events that result in the formation of the precipitate, a solid form of residue.

Explanation:

The reaction of an excess of aqueous silver nitrate with aqueous barium chloride is as follows below:

               AgNO₃ + BaCl₂ → 2 AgCl ↓ +Ba(NO₃)₂

The precipitates of silver chloride are formed in the above reaction.

The precipitates which are removed by filtration are Ba⁺² + NO₃²⁻ as follows below.

                         Ba(NO₃)₂ → Ba⁺² + NO₃²⁻

Hence, the correct option is (c) Ba⁺² and NO³⁻ only.
