Which of following 0.10 M aqueous solution will have the lowest freezing point?
Thus, for a given solvent and given concentration, ΔTf is directly porportional to i (van’t hoff factor) i.e. maximum Tf (and hence lowest freezing point) will correspond to maximum value of i. Hence, 0.10M(≈0.10m) aqueous solution will have the lowest feezing point.
Which aqueous solution will have the lowest freezing point?
Remember, the greater the concentration of particles, the lower the freezing point will be. 0.1mCaI2 will have the lowest freezing point, followed by 0.1mNaCl, and the highest of the three solutions will be 0.1mC6H12O6, but all three of them will have a lower freezing point than pure water.
Which of the following 0.1 M aqueous solution will have lower freezing point?
Sodium chloride gives two ions and potassium sulphate gives three ions per formula unit. Therefore, the effective number of particles is maximum in potassium sulphate, and it shows the maximum depression in freezing point.
Which of the following 0.10 M aqueous solution will have the largest freezing point?
ΔTf (freezing point depression) is a colligative property and depends upon the van’t Hoff factor (i) i,e., number of ions given by the electrolyte in aqueous solution. Hence, Al2(SO4)3 will exhibit largest freezing point depression due to the highest value of i.
Which of the following aqueous solutions will have the highest depression in freezing point?
So the depression in freezing point is 0.003. So here the lowest depression in freezing point has sucrose, hence it will have the highest freezing point.
Which of the following aqueous solution is the highest boiling point?
Answer: (b) As we know greater the value of van’t Hoff factor higher will be the elevation in boiling point and hence higher will be the boiling point of solution. Hence, 1.0 M Na2St4 has highest value of boiling point.
Why does solute lower freezing point?
Truong-Son N. Nonvolatile solutes lower the freezing point by blocking the solvent particles from congregating. And thus, nonvolatile solutes make it harder to freeze, lowering the freezing point. The same solutes will also raise the boiling point.
Which is aqueous solution of KI?
Potassium Iodide, 10 Percent (w/v) Aqueous Solution is refered to by the chemical formula KI and is an inorganic compound. Used as a component in film photography before the discovery of silver iodide, it is also used in the electrolyte of dye sensitized solar cells.
Which aqueous solution will have the lowest freezing point quizlet?
Which aqueous solution has the lowest freezing point? The solution with the lowest freezing point is 0.25 m AlCl3.
Which 0.1 M aqueous solution is the best conductor of electricity?
D. 0.1 M aq. NaCl. As the given electrolytes have same concentration and atmospheric parameters, therefore the one with maximum degree of dissociation would be the best conductor of electricity.
Which has maximum freezing point?
However, ammonia remains as it is with i=1. So, depression in the freezing point would be least for ammonia and its solution would have the maximum freezing point.
Which has the minimum freezing point?
van’t Hoff factor, i = 2 for NaCl, so concentration = 0.02, which is maximum in the present case. Hence, ΔTf is maximum or freezing point is minimum in 0.01 m NaCl. The aqueous solution of 0.01M NaCl has a minimum freezing point.
Which one has the largest freezing point depression?
1.0 m KBr has the largest freezing point depression.
Which of the following solution has the lowest freezing point?
0.1m Na2SO4 will have the lowest freezing point as it contains maximum number of ions in solution.
Is 0.1 molal aqueous solution of a weak acid is 30% ionized?
If K_(f) for water is 1.86^(@)C//m, the freezing point of the solution will be. Since the freezing point of water is 0∘C, the freezing point of solution will be -0.24∘C.
Which has the highest freezing point at 1 atmosphere group of answer choices?
As \[FeC{l_3}\] solution comprises the maximum number of solute particles, its freezing point will be the lowest and sugar solution comprises the minimum number of solute particles so its freezing point will be the highest. So, the correct answer is Option B.
Which of the following solution will Highest freezing point?
The lowest van’t hoff factor will result in the least depression in freezing point and hence that solution will have the highest freezing point. Hence, the correct option is D, glucose.
Which of the following has maximum boiling point?
Hence, hexane (C6H14) has the maximum boiling point.
Which of the following aqueous solution will have minimum elevation in boiling point?
Here 0.05M NaCl is of the following aqueous solution will have minimum elevation in boiling point. Therefore it is solution which can solvent is water and mostly show in the part of the chemical equation by the appending and also the relevant chemical formula support to the major solution with no trouble of it.
Which of the following aqueous solution will have highest boiling point 0.1 M urea?
Answer: b option is the correct answer.
How do you calculate freezing point?
The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.
What is the normal freezing point of water?
The freezing point is the temperature at which a liquid turns to a solid. The freezing point at which water — a liquid — turns to ice — a solid — is 32°F (0°C).
Why is freezing point depression a colligative property?
The freezing point depression thus is called a colligative property. The explanation for the freezing point depression is then simply that as solvent molecules leave the liquid and join the solid, they leave behind a smaller volume of liquid in which the solute particles can roam.
What color is an aqueous solution of KI?
Colorless Concentration or Composition Notes 10% (w/v) Solvent or Matrix Aqueous Solution Color Colorless Quantity 500mL Chemical Name or Material Potassium Iodide.
Is KI aqueous?
They contain two aqueous reactants, one aqueous product, and one solid product. In this reaction, two soluble products, Pb(NO3)2 and KI, combine to form one soluble product, KNO3, and one insoluble product, PbI2. abbreviations are as follows: s = solid; l = liquid; g = gaseous; aq = aqueous, or soluble in water.
Is KI soluble in water?
Water.
What is the freezing point of aqueous glucose?
The freezing point of a glucose solution ( C6H12O6;molar mass= 180.0 g/mole) is – 10.3 degree C .
Which aqueous solution has the lowest boiling point?
The solution with the lowest boiling point is 0.50 m LiCl (Choice C).
Which solution has the highest freezing point quizlet?
CH3CH2OH is non-electrolyte and doesn’t dissociate into ions and therefore it’s 1.5m concentration is the lowest concentration of dissolved species amongst the answer choices and this solution will have the smallest decrease (depression) in its freezing point leaving it with the overall highest freezing point.
