Answer:
The complete: Answer in…a $strongTag7 $… as given below:
Names of Salts | Soluble in Water | Insoluble in Water |
1. CuBr2( copper(II)bromide) |
YES..soluble | |
2. CuCO3 ( cupric carbonate) |
Yes, Insoluble. | |
3. AgBr ( Silver bromide) |
Yes, Insoluble. | |
4. BaSO4( barium sulfate ) |
Yes, Insoluble | |
5. NH4Br ( ammonium bromide ) |
Yes, soluble | |
6. Pb(NO3)2( Lead (II) Nitrate ) |
Yes, soluble |
Explanation:
The complete Explanation for the above: Answers.
Since copper (II) bromide(CuBr2) dissociates into ions in its aqueous solution, it is soluble in water.
Copper (II), carbonate ( CuCO3 ) has more lattice than hydration energy. It is insoluble for water.
We know that all silver halides ions are insoluble in liquid water. This is due to a low electronegativity between the Ag+ and the Br
– ions. Because they are very similar, the ionic radius between the silver ions and the bromideions is very high and forms the ionic bond. It becomes very difficult to separate them. So silver bromide becomes insoluble in water.
Because the ions are similar in size, the force of attraction between them is weak and so they do not form strong ionic bonds. They have lower hydration energy and higher lattice energy. Thus, the molecules almost become insoluble in water.
Since ammonium bromide ( NH4Br ) can be dissociated into ions in its aqueous
solution, it is able to become : soluble when it comes to water.
We will see that Pb2+ and NO3 – ions make up the salt: Pb(NO3)2. This is ionic, soluble in water.
