Answer

General guidance

Concepts and reason
The concept used to solve this problem is determined the presence of ions in given salt.

Fundamentals

General rule for the solubility of salt is as follows:

1.If the salt contains , Li, Na, K, NH, C,H,C00, CT, Br, 1, SONO, ions then it is soluble in water.

2.If the salt contains , Ag*, Pb2*, Ca2+, Hg?, Ba2+, Sr2+, CO,.,S2, OHĽ PO ions then it is in-soluble in water.

Step-by-step

Step 1 of 3

Part 1

Thus BaSOis in-soluble in water.


a.BaSOis in-soluble salt because it containsions.

b.is soluble salt because it contain nitrate ion.

c.is a soluble salt because it contains sodium ion.

d.is soluble salt because it contains lithium ion.

Step 2 of 3

Part 2

Thus the soluble salt is Co(NO3)2.


a.is in-soluble salt because it containsions.

b.is soluble salt because it contain nitrate ion.

c.is an in- soluble salt because it contains ion.

d.is in-soluble salt because it contains ion.

Step 3 of 3

Part 3

Thus Cu(NOx),(aq) + Li,PO,(aq) → Cu,(PO.),(s) +LINO, (aq) is an example of precipitation reaction.


Precipitation reaction means formation of Precipitation; when solutions of two ionic substances are mixed and a precipitate falls from solution, the reaction is known as Precipitation reaction. The reaction of barium hydroxide and sodium sulfate is an example of Precipitation reaction.

Answer

Part 1

Thus BaSOis in-soluble in water.

Part 2

Thus the soluble salt is Co(NO3)2.

Part 3

Thus Cu(NOx),(aq) + Li,PO,(aq) → Cu,(PO.),(s) +LINO, (aq) is an example of precipitation reaction.
