What property does not effect the rate of dissolving?
colour is a physical property that has no effect on the rate of dissolving
Will a substance dissolve faster if it is ground into powder first?
The dissolution rate of a substance is affected by the surface area that can react with the liquid it is dissolving in. Powdering it increases the surface area so it increases the dissolving rate.
Is there any way to change the average amount of radiation emitted from a radioactive substance?
No, the average amount of radiation emitted from a radioactive substance is inherent to the substance's decay process and cannot be changed. The rate of decay is measured by the substance's half-life, which is a fixed characteristic of the radioactive material.
What will affect both the rate of dissolving and the solubility of a solid in a liquid?
Temperature and particle size of the solid will affect both the rate of dissolving and the solubility in a liquid. Higher temperatures generally increase the rate of dissolving and solubility, while smaller particles increase the rate of dissolving due to increased surface area available for interaction with the solvent.
How does the rate of dissolution and crystallization compare at equilibrium?
At equilibrium, the rate of dissolution is equal to the rate of crystallization. This means that the amount of solute dissolving is the same as the amount of solute precipitating out of solution, leading to a dynamic equilibrium where there is no net change in the concentration of the solution.
What property does not effect the rate of dissolving?
colour is a physical property that has no effect on the rate of dissolving
What effect do temperature and stirring have on the rate of dissolving?
Stirring and increasing temperature increase the dissolving rate.
Does purity effect dissolving rate and how?
Yes, the purity of a substance can affect its dissolving rate. Higher purity substances typically dissolve faster because there are fewer impurities or other substances present that might interfere with the dissolving process. Impurities can slow down the dissolving rate by creating barriers for the solvent to interact with the solute particles.
Does shape of solids affect the rate of dissolving?
Yes; the dissolution rate is increased when a substance is as small particles.
How does solubility affect the rate of dissolving?
A very soluble substance is dissolved faster.
How does temperature effect the rate od dissolving sugar?
it makes it faster to dissolve
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in?
When the dissolving rate equals the rate at which molecules come out of solution, the solution is in a state of dynamic equilibrium. This means that the amount of solute dissolving is equal to the amount of solute precipitating out of solution, resulting in a stable concentration of solute.
What is the state in which the rate of dissolving is equal to the rate of precipitation?
The state where the rate of dissolving is equal to the rate of precipitation is called equilibrium. This means that the amount of solute being dissolved is equal to the amount being deposited back as a solid.
What are three factors that affect the rate at which a substance dissolves?
Three factors that affect the rate at which a substance dissolves are temperature, surface area of the substance, and the stirring or agitation of the solution. Increasing the temperature generally increases the rate of dissolving, while breaking the substance into smaller pieces or increasing its surface area also speeds up the process. Stirring or agitation helps to bring fresh solvent into contact with the solute, enhancing the dissolving rate.
Will a substance dissolve faster if it is ground into powder first?
The dissolution rate of a substance is affected by the surface area that can react with the liquid it is dissolving in. Powdering it increases the surface area so it increases the dissolving rate.
What affects the rate at which a substance dissolves into another substance?
the amount of space the substance takes up
What are the rates that effect the rate of dissolving?
The polarity of solute and solvent, the concentration, the temperature.
