How can you reduce the rate of dissolution?
You can decrease the rate of solvation by cooling the solution, but the technique works only to the point at which the solution freezes; then it stops completely. Cooling is also complicated by the fact that some solvation reactions produce heat and some consume it.
What are the factors that affect the rate of dissolution solution?
The rate of dissolution, in contrast, is a measure of how fast a solute dissolves in a solvent. There are three factors that affect the rate of dissolution: (1) the surface area of the solute, (2) the temperature of the solvent, and (3) the amount of agitation that occurs when the solute and the solvent are mixed.
Which of the following causes the rate of dissolution to increase?
Stirring: Stirring the solute and solvent creates more contact between the solute and the solvent particles. This increases the rate of dissolution.
How does solubility affect dissolution rate?
Solubility and dissol ution rate are two distinct phenomena. Dissolution rate is a kinetic process. A solute may have poor solubility in a solvent, yet its dissolution rate may be rapid. Conversely, a solute can be very soluble, yet require a protracted amount of time to arrive at the final, saturation concentration.
How does decreasing the size of the solute particles increases the rate of dissolving?
Size of the particles — When a solute dissolves, the action takes place only at the surface of each particle. When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution.
Which of the following would decrease the rate in which a solid dissolves in a liquid?
Cards
| Term 1. Which of the following would decrease the rate of solution when dissolving a solid in water? | Definition use a single cube of solid |
|---|---|
| Term 48. Which of the following causes a change in state from liquid to gas? | Definition high kinetic energy |
Why does temperature affects the rate of dissolution?
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
What slows the rate of solution when dissolving a gas into a liquid?
What slows the rate of solution when dissolving a gas into a liquid? Cold temperature.
