Answer : The precipitate will not be formed when these solutions are mixed.
Explanation :
The chemical equation for the reaction of calcium chloride and lithium sulfate follows:
![CaCl_2(aq)+Li_2SO_4(aq)\rightarrow 2LiCl(aq)+CaSO_4(s)](https://tex.z-dn.net/?f=CaCl_2%28aq%29%2BLi_2SO_4%28aq%29%5Crightarrow%202LiCl%28aq%29%2BCaSO_4%28s%29)
We are given:
Concentration of calcium ion = ![2.1\times 10^{-5}M](https://tex.z-dn.net/?f=2.1%5Ctimes%2010%5E%7B-5%7DM)
Concentration of sulfate ion = ![4.75\times 10^{-5}M](https://tex.z-dn.net/?f=4.75%5Ctimes%2010%5E%7B-5%7DM)
![K_{sp}=2.4\times 10^{-5}](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D2.4%5Ctimes%2010%5E%7B-5%7D)
The salt produced is calcium sulfate.
The equation follows:
![CaSO_4(s)\rightleftharpoons Ca^{2+}(aq)+SO_4^{2-}(aq)](https://tex.z-dn.net/?f=CaSO_4%28s%29%5Crightleftharpoons%20Ca%5E%7B2%2B%7D%28aq%29%2BSO_4%5E%7B2-%7D%28aq%29)
The expression of
(ionic product) for above equation follows:
![Q_{sp}=[Ca^{2+}]\times [SO_4^{2-}]](https://tex.z-dn.net/?f=Q_%7Bsp%7D%3D%5BCa%5E%7B2%2B%7D%5D%5Ctimes%20%5BSO_4%5E%7B2-%7D%5D)
Putting values of the concentrations in above expression, we get:
![Q_{sp}=(2.1\times 10^{-5})\times (4.75\times 10^{-5})\\\\Q_{sp}=9.9\times 10^{-10}](https://tex.z-dn.net/?f=Q_%7Bsp%7D%3D%282.1%5Ctimes%2010%5E%7B-5%7D%29%5Ctimes%20%284.75%5Ctimes%2010%5E%7B-5%7D%29%5C%5C%5C%5CQ_%7Bsp%7D%3D9.9%5Ctimes%2010%5E%7B-10%7D)
There are 3 conditions:
- When
; the reaction is product favored. (No precipitation) - When
; the reaction is reactant favored. (Precipitation) - When
; the reaction is in equilibrium. (Sparingly soluble)
As, the
. The above reaction is product favored. This means that no salt or precipitate will be formed.
Hence, the precipitate will not be formed when these solutions are mixed.
The answer is C lol i just guessed on USA test prep and I was right
Answer:
Abiotic means non'living. Some factors in an environment that are abiotic include sunlight, rocks, wind, anything non'living in the environment.
