If u increase the pressure on a liquid or gas, u are forcing the molecules closer to each other in a space smaller than what it usually exists as. When the molecules come closer the spaces between them are highly reduced due to which there is less space for the molecules of solids or other liquids to fit into the spaces as it usually can. Hence it seems that the liquid or gas cannot dissolve a certain solid/liquid with the rate which it used to(it is lesser). hence u say that the solubility has reduced.
Pressure= 1/solubility
Pressure doesn't affect the rate of dissolving :)
Henrys law... increased pressure will cause more gas to dissolve in a liquid.
The more a solution is agitated, the faster the rate of the solution The smaller the particle size, the faster it will dissolve The higher the temperature, the faster rate of dissolving
effect of temperature on solubility - solid in liquid-most solid become more soluble in a liquid as the temperature rises. effect of pressure on solubility -pressure changes have little effect on solubility if the solute is a liquid or a solid.
by adding the rate
Both stirring and heating increase the rate of dissolving
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
Reducing Aire Pressure
A very soluble substance is dissolved faster.
In a high volume of solution dissolving is faster.
Reducing the air pressure on the solution
The higher the temperature, the greater the rate of dissolving.
The more a solution is agitated, the faster the rate of the solution The smaller the particle size, the faster it will dissolve The higher the temperature, the faster rate of dissolving
Its numbers of protrons
Heating or stirring will normally increase the rate at which a soluble solid dissolves in liquid. Heating will also normally increase the amount of solute that can be retained in solution.
Yes, in fact stirring does increase the rate of dissolving [or dissolution] of solids.
Temperature afftects the solubility...see Henrys Law and chemical kinetics
How do the following factors affect the rate of dissolving for temperature change
effect of temperature on solubility - solid in liquid-most solid become more soluble in a liquid as the temperature rises. effect of pressure on solubility -pressure changes have little effect on solubility if the solute is a liquid or a solid.
