When mercuric iodide is added to an aqueous solution of potassium iodide freezing point is raised why?
Freezing point of the solution will increase. Mercuric Iodide will react with Potassium Iodide to form dipotassium tetraiodomercury. The reaction is given below :2KI + HgI2 = K2[HgI4]This association will decrease the number of ions in the solution as a result of which Van't Hoff Factor (i) will decrease as n decreases from 4 to 3.Now, Freezing point depression when a solute is added to a solvent is given by ΔT = i Kf mClearly now i has decreased from when it was an aqueous KI solution to when HgI is added so ΔT is less now, hence less depression in freezing point which means a higher freezing point.Hence the freezing point of solution will increase.Note: Van't Hoff factor (i) =1+alpha(n-1) where alpha=dissociation degree and n is the no of ions dissociatedHope you understand the reasoning behind it now.
Calculate the boiling point elevation of an aqueous solution of 0.14 m glucose?
Glucose is an covalent compound and doesn't break apart like ionic compounds. so the von hoff factor is only 1 mKfi therefore 0.14 x 1.86= 0.26 lower than the original freezing point
What are the factor that effect the formation of substitutional solid solution?
atomic radius Valence electrons
Which factor will have little effect on the solubility of saturated solutions?
the amount of extra time spent stirring the solution
Definition of normality as concerned to chemistry?
Normality of a solution is defined as the molar concentration divided by an equivalent factor

It is: 1
Why is 24 not a factor of 12?
That simply means that there is no integer solution to:24n = 12 For comparison, 4 IS a factor; so the equation: 4n = 12 DOES have an integer solution.

No solution in integers.
You are planning an experiment to find out whether the rate at which water freezes depends on the shape of its container What is the manipulated variable and what is the responding variable?
The manipulated variable is what you change (the shape of the container) The responding variable is the result (the temperature at which the water in the container freezes). (Don't forget the time factor!)
What is a big factor in coffee production?
the weather is a big factor--from freezes, to drought, to too much rain. For example, Hurricane Georges and Tropical Storm Mitch blew through Central America in 1998, causing widespread damage.
