What is non volitile solute?
a non volatile solute will not evaporate
A liquid with a solid dissolved in it is called a solution How might you get a solid back from a solution?
Boiling off the solvent to vapour if the solute is not too volatile.
When a solute dissolves into water the freezing point does what?
When a solute is dissolved into water the freezing point will lower. In other words, if you want to freeze a solution of water and some solute, you will have to cool it beyond the freezing point of pure water.
What effect does adding a solute to a solvent have on the freezing point of the solvent?
the temperature at which the solution freezes is lowered.
What is the solvent and solute in liquid nitrogen?
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
When a non volatile solute added to a volatile liquid what happened to the freezing point and osmotic pressure?
The freezing point is lowered.
What is a volatile and non volatile solute?
volatile will evaporate
What is the effect of the addition of a non volatile solute?
what is the effect of the addition of a non volatile solute to the boiling point of water?
What is the tendency of a solute to change the melting point of a solid called?
The answer is "Freezing point depression" on Apex
What is non volitile solute?
a non volatile solute will not evaporate
How are freezing point depression and boiling point elevation useful?
the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.
Why can water stay liquid below freezing?
Yes, with the addition of a solute or by increasing pressure water can be kept liquid below its normal freezing point. Water can also be supercooled, but will freeze instantly if it is disturbed.
A liquid with a solid dissolved in it is called a solution How might you get a solid back from a solution?
Boiling off the solvent to vapour if the solute is not too volatile.
Why is it when a solute is added to a pure liquid the boiling point increases and the freezing point decreases?
Boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. The vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid. At the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
A solute makes the freezing point of a solution lower than the freezing point of the pure solvent because?
The phenomenon you're describing is generally referred to as freezing-point depression, the lowering of the freeze point of a liquid (or solvent) by adding another compound. Freezing point depression is a phenomenon driven by entropic changes in the system containing solvent and solute. As the system is frozen, the solvent forms crystals of high purity regardless of solute molecules being present while solvent crystallizes. Replacement of any solute in the crystal with a solvent molecule takes place spontaneously, since the inability of solute molecules to fit well into the ordered crystal makes the solute-solvent substitution thermodynamically favorable. As the freezing proceeds, solvent molecules continue to leave the liquid state and incorporate into the solid crystal, with each such occurrence leaving behind a smaller volume of liquid in which solute molecules can occupy. The shrinking of liquid volume occupied by a fixed number of solute molecules reduces the dispersion of solute molecules in the liquid, resulting in a reduction of entropy of the solute molecules. Thus, additional energy is required to match the reduced entropy of the solute molecules with that of the solid solvent crystal. The energy required (versus pure solvent) to gap the entropic difference (thus difference in chemical potential) to establish equilibrium but at a freezing temperature lower than that of the pure substance. Note that at low solute concentrations, freezing point depression is a property that depends solely of the number of solute particles and physical properties of the solute. Such properties are called colligative properties.
Does plain water evaporate quicker than salt water?
Yes, this is based on the colligative properties of liquid. Whenever, a solute( like salt) is added to a solvent(like water), the following happen to the properties of the solvent. 1. Elevation of freezing point. 2. Depression in freezing point
