The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
What else can I help you with?
Do solutes increase or decrease the boiling point of a solvent?
No; solutes don't decrease the boiling point of the solvent, they increase it! Solutes decrease the melting point of the solvent! Think of it this way: low goes lower (melting point) and high goes higher (boiling point).
Are polar solutes soluble in nonpolar solvents?
No, polar solutes are generally not soluble in nonpolar solvents.
Do all solutes behave on the same way?
No, not all solutes behave the same way in a solution. Different solutes can have different effects on properties such as boiling point, freezing point, and osmotic pressure based on their molecular structure and interactions with the solvent.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
How does adding salt to water affect the temperature?
It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.
How do solutes change solvents?
They can change by lowering the freezing point.
What are two ways that solutes affect the properties of solvent?
Solutes lower the freezing point and raise the boiling point of a solvent! :)
Do solutes increase or decrease the boiling point of a solvent?
No; solutes don't decrease the boiling point of the solvent, they increase it! Solutes decrease the melting point of the solvent! Think of it this way: low goes lower (melting point) and high goes higher (boiling point).
Are polar solutes soluble in nonpolar solvents?
No, polar solutes are generally not soluble in nonpolar solvents.
What lowers the freezing point and raises the boiling point?
Adding solutes, such as salt or sugar, to a solvent can lower the freezing point and raise the boiling point. This phenomenon is known as freezing point depression and boiling point elevation, respectively. The presence of solutes disrupts the normal crystal structure in the solvent, requiring lower temperatures to freeze and higher temperatures to boil.
Why does water freeze faster than coke and maple syrup?
Because water is pure; solutes decrease the freezing point of solvents.
How does the principle of like dissolves like explain the differing solubilities of solutes in various solvents?
Generally polar solutes are dissolved in polar solvents and nonpolar solutes are dissolved in nonpolar solvents.
How does the principle like dissolves like explain the differing solubilities of solutes in various solvents?
Generally polar solutes are dissolved in polar solvents and nonpolar solutes are dissolved in nonpolar solvents.
What are the solutes in air and what are the solvents?
Solutes are substances dissolved in a solvent.
Do all solutes behave on the same way?
No, not all solutes behave the same way in a solution. Different solutes can have different effects on properties such as boiling point, freezing point, and osmotic pressure based on their molecular structure and interactions with the solvent.
What is the expression that sums up the dissolving of polar or non polar solvents and solutes?
The term that summarizes the dissolving process of polar or nonpolar solvents and solutes is "like dissolves like." This means that polar solvents tend to dissolve polar solutes, while nonpolar solvents dissolve nonpolar solutes due to their similar intermolecular forces.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
