Are collisions between solvent molecules and solute are more frequent at lower or higher temperatures?
Collisions between solvent molecules and solute are more frequent at higher than lower temperatures.
Why do you use a solvent in chromatography?
A solute will dissolve in a solvent when the attractive intermolecular forces between the molecules of the solvent and the molecules of the solute are greater than the attractive forces between one solute molecule and another. Thus the solute is effectively 'pulled apart' (on a molecular level at least) by the solvent and it's molecules become 'suspended' between the molecules of the solvent at which point the solute is said to be in solution or dissolved.
What is the cage effect of solvent?
The cage effect describes how molecules are affected by their surroundings. For example, reactants in a liquid can be trapped in a "cage" of solvent molecules. In this cage, many collisions occur before squeezing out into a new cage. If there are other reactants in this cage, a reaction is likely to occur, but if there isn't, these reactants won't react until they squeeze out again.
What needs to happen for a solute to dissolve in a particular solvent?
The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together.
What 2 solute molecules mixed with the solvent molecules in a solution cause the freezing point of a solution to be than it is for an equal volume of pure?
lower, solvent, lower, solvent
Are collisions between solvent molecules and solute are more frequent at lower or higher temperatures?
Collisions between solvent molecules and solute are more frequent at higher than lower temperatures.
Raising the temperature of a solvent causes solvent-solvent collisions to become?
Raising solvent temperature causes solvent-solute collisions to become more frequent and more energetic.
Why does stirring increase the rate of dissolution?
Thr number of collisions between solute and solvent molecules is increased.
Which determines the rate at which a solid dissolves in a liquid solvent?
the frequency and energy of the collisions between the solute and solvent particles
Why does hot chocolate powder dissolve more rapidly in hot water than cold?
The majority of solid substances are dissolved faster at high temperature; the number of collisions between solute molecules and solvent molecules is increased.
Why does hot chocolate dissolve more rapidly in hot water than in cold water?
The majority of solid substances are dissolved faster at high temperature; the number of collisions between solute molecules and solvent molecules is increased.
How does stirring faster the solubility of solutes in a solvent?
Apex - It makes the water molecules bump into the solute more. ^.^
Which determines the rate at which a solid solute dissolves in a liquid solvent?
the frequency and energy of the collisions between the solute and solvent particles
Why sugar dissolves fast on heating?
When sugar is dissolved in any solvent (i.e. Water or Milk), its molecule tries to adjust themselves between the molecules of the solvent... When the solvent is heated the distance between the molecules is increased and the sugar molecules are easily dissolved as compared to when the solvent is cool or at normal temperature...
How does the boiling point of a solvent change when a solute is dissolved in it how does the freezing point change?
The boiling point rises and the freezing point lowers.The reason being, when a solute dissolves in a solvent, the solute molecules wedge themselves between the solvent molecules. In order for the solvent to freeze, its molecules have to get close enough together to form a solid. However, the solute molecules are in the way. As a result, it requires much colder temperatures for the solvent molecules to form a solid, despite the hindrance of the solute's molecules. The same sort of thing happens when trying to boil the solvent, only instead of holding the solvent molecules apart, the solute molecules end up holding them together, preventing them from boiling. Therefore, a more energy is needed to break the bond between solvent and solute, which allows the solvent to boil.
When a solute is dissolved in a solvent what happens?
when solute is dissolved in a solvent...the molecules of the solute starts diffusing between the particles of the solute.
