Answer:
Following are the solution to the given question:
Explanation:
In the aqueous solution of
ion is used to represent a
.
It is used to form a complex with iodide ions as
.
Conversion reaction:
![[Hg(H_2O)_4]^{2+} +4I^{-} \to [HgI_4]^{2-}+4H_20](https://tex.z-dn.net/?f=%5BHg%28H_2O%29_4%5D%5E%7B2%2B%7D%20%2B4I%5E%7B-%7D%20%5Cto%20%5BHgI_4%5D%5E%7B2-%7D%2B4H_20)
Following are the formation constants:
![k_f=\frac{[HgI_4]^{2-}}{[Hg(H_2O)_4]^{2+} [I^{-}]^4}](https://tex.z-dn.net/?f=k_f%3D%5Cfrac%7B%5BHgI_4%5D%5E%7B2-%7D%7D%7B%5BHg%28H_2O%29_4%5D%5E%7B2%2B%7D%20%5BI%5E%7B-%7D%5D%5E4%7D)
Following are the first step to the conversion:
![[Hg(H_2O)_4]^{2+} +I^{-} \to [HgI(H_2O)_3]^{+}+H_20](https://tex.z-dn.net/?f=%5BHg%28H_2O%29_4%5D%5E%7B2%2B%7D%20%2BI%5E%7B-%7D%20%5Cto%20%5BHgI%28H_2O%29_3%5D%5E%7B%2B%7D%2BH_20)
Answer:
See explanation
Explanation:
Iodine solution is used to test for starch. A positive test for starch gives a blue-black color.
The fact that the color of the apple remained the same is indicative of the fact that starch was not contained in the apple.
A change in the color of potato indicates the presence of starch in the potato.
The fact that iodine did not react with apple should not be taken to mean that apples contain no starch at all. Starch changes gradually to sugar as fruits ripen. This is why the apple gave a negative test for starch.
Answer:
B
Explanation:
Smaller pieces results in a larger surface area, therefore the answer is beaker B.
