When is mercury iodide added to an aqueous solution?
Add mercury iodide to the aqueous solution of KI, freezing point rise. So, the correct answer is « Option A ».
When mercury iodide is added to KI aqueous solution, the freezing point will rise, why?
Due to the formation of complex ions between mercury iodide and I-, the number of moles Particle count reduced from 4 to 3. Hence the magnitude of the collinearity property (ΔTfandΔTb) decreases. Therefore, the freezing point is raised and the boiling point is lowered.
What is the freezing point of potassium iodide when mercury iodide is added to an aqueous solution of mercury iodide?
freezing point.
Why is KI added to the aqueous iodine solution?
The increased solubility of iodine in aqueous KI is due to Formation of KI3.
What happens when you add mercuric chloride to a potassium iodide solution?
When mercury(II) chloride is mixed with potassium iodide. … this Mercury iodide creates an orange precipitate inside the vortex, creating a tornado-like effect. Then the precipitate disappears because it mixes with excess potassium iodide.

How do you prepare an aqueous iodine solution. Write a chemical reaction?
Dissolve KI in about 20-30 mL of distilled water. Add the iodine and heat gently with constant stirring until the iodine dissolves dissolve. Dilute to 100 ml with distilled water.
What type of container is best for iodine?
3 Storage conditions Iodine topical solution should be stored in Lightfast container Iodine tincture should be stored in airtight containers at a temperature not exceeding 35 °C.
What is the role of potassium iodide in aqueous iodine solution?
KI (potassium iodide) is a stable (non-radioactive) iodized salt, Can help stop radioactive iodine from being absorbed by the thyroid, thereby protecting this gland from radiation damage. The thyroid is the most sensitive part of the body to radioactive iodine.
Which of the following aqueous solutions has the highest freezing point?
Now, from the above compounds, ${C_2}{H_5}OH$ has the lowest concentration. This means that it will have the smallest depression at freezing point, which means it will have the highest freezing point. Therefore, option (Second) is the correct option.
Which equimolar concentrated solution has the highest freezing point?
The freezing point of an equimolar solution is the highest:
- B. Ca(No3)2.
- C. La(NO3)3.
- La(NO3)3 will provide four ions, thus further lowering the freezing point, while glucose provides only one particle, so the freezing point depression is minimal.
What is the freezing point of urea solution?
209) The freezing point of urea solution is -0.6°C.
When adding HgI2 to an aqueous solution of KI, which of the following statements is incorrect?
(a) yes Incorrect Due to the formation of the complex 2KI+HgI2→K2HgI4, the number of particles will decrease, so the freezing point will increase.
Why does adding HgI2 to aqueous KI increase osmotic pressure?
When mercury (mercury) is added to an aqueous solution of KI (potassium iodide), the osmotic pressure of the solution increases due to:- The ratio of the number or concentration of non-volatile solute particles on which polymerizability depends .
What are the Colligative properties?
Collateral properties include Vapor Pressure Depression, Boiling Point Raise, Freezing Point Depression, and Osmotic Pressure.
What is the official definition of strong iodine solution?

Why should iodine solutions be stored in the dark?
The reaction mixture should be protected from light before titration Because light accelerates the side reaction of oxidation of iodide ions to iodine by atmospheric oxygen.
Will iodine react with plastic?
Iodine molecules easily get between plastic molecules And thus dye the fragments all the way. Plastics, in turn, provide a unique environment for iodine, like air or water, and give iodine its brown or pink color.
