Which Of The Following Aqua Solution Has Maximum Freezing Point?

Which of the following Aqua solution has minimum freezing point?

The aqueous solution of 0.01M NaCl has a minimum freezing point..

Which has maximum boiling point at one atmospheric pressure?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude.

What Does lowest freezing point mean?

A solution will have a lower freezing point than a pure solvent. The freezing point is the temperature at which the liquid changes to a solid. … This is true for any solute added to a solvent; the freezing point of the solution will be lower than the freezing point of the pure solvent (without the solute).

Which of the following Aqua solution has highest freezing point?

Video Explanation Sucrose is non-electrolyte and so i=1. The highest freezing point will be of the solution having the lowest ΔTf value. Therefore, 0. 01 M NaCl solution will have the highest freezing point.

Which has highest freezing point 1m glucose?

Hence depression in freezing point will be minimum in glucose. Therefore, 1M glucose will have highest freezing point.

Which aqueous solution has minimum depression freezing point?

The aqueous solution of 0.01M NaCl has a minimum freezing point.

Which of the following 0.1 M aqueous solution will have the lowest 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.

How do you calculate change in 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.

Why does solute lower freezing point?

The presence of a solute lowers the freezing point of any solvent; this effect is called freezing-point depression. … The introduction of a solute reduces the activity of the liquid phase solvent, thereby reducing the rate of freezing.

Which solution has highest boiling point?

0.1 M MgCl2 solution has the highest boiling point. Elevation in the boiling point is a colligative property and depends on the number of solute particles. 1 mole of MgCl2 on dissociation in water gives 3 moles of ions. This is maximum number of particles as compared to other solutes.

Which has lowest freezing point?

Video Explanation Depression in freezing point is a colligative property. Thus, the compounds which produce maximum ions has the least freezing point. Thus, 1% CaCl2 has the least freezing point.

Which has higher boiling point 0.1 m nacl or 0.1 m bacl2?

Bacl2 will have higher boiling point as boiling point is a colligative property . And the van’t hoff factor of nacl is more than bacl2. Consequently, 0.1M bacl2 will have higher boiling point than 0.1M nacl.

Which functional group has highest boiling point?

Lesson SummaryEthers have a higher boiling point than alkanes because they have both London dispersion forces and dipole-dipole interactions.Amines have a higher boiling point than both ethers and alkanes because they have London dispersion forces, dipole-dipole attractions, and hydrogen bonding.More items…

How do you find freezing point?

Strategy:Step 1: Calculate the freezing point depression of benzene. Tf = (Freezing point of pure solvent) – (Freezing point of solution) … Step 2 : Calculate the molal concentration of the solution. molality = moles of solute / kg of solvent. … Step 3: Calculate Kf of the solution. Tf = (Kf) (m)

Is freezing point depression negative?

Kf is called the freezing point depression constant or cryoscopic constant. Sometimes this formula doesn’t have the negative sign and you simply need to remember that freezing point goes down.

Which one of these has the highest freezing point?

Hence depression in freezing point will be minimum in glucose. Therefore, 1M glucose will have highest freezing point.
