Why does reducing solute size particle size increase the speed at which the solute dissolves in water?
For the amount of material in the particle the surface area of a small particle is greater than a larger particle. Said another way, the surface area per unit volume is greater for a smaller particle. Dissolving speed is related to the surface area. Therefore a smaller particle dissolves faster than a larger particle.
What speeds up dissolving?
To speed up the dissolving of a solute you can, among many options:Heat up the mixtureStir the mixtureAdd more solute, then filter off the excessCrush the solute to give it a greater surface area
How is the surface area of a solid related to its solubility?
A greater surface area means a greater portion of the solid(solute) is in contact with the solvent at a given time. This increases the area in which interaction between the 2 substances can take place, and thus the rate at which the solute dissolves.
What are three methods to speed up a chemical reaction?
* breaking a solid into something smaller (to increase its surface area) * make the solution more concentrated, * increase the temperature. Other methods for increasing the rate of reaction are incrasing the pressure and adding a catalyst.
What three ways to increase the dissolving rate of a solid?
Surface Area/Quantity of Solvent, Temperature, and Agitation
How does breaking up a solid speed dissolving in liquid?
By breaking up the solid, you are creating more surface area. Therefore, increasing the surface area will speed up dissolution.
What will increasing the surface area of a solid do to the dissolving rate of that solid?
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
How does grinding speed up dissolving?
By grinding the surface area of the sample increase and the contact between the solvent and solute is improved.
Why does crushing a substance speed up reaction rate?
You are increasing the surface area for the substance to react
Why does crushing a solid increase the speed at which the solid dissolves?
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
How does surface area affect dissolving?
Directly proportional
How does increasing the amount of solvent speed up the dissolving process?
By breaking up the solute, the surface area between the solute and solvent is increased, meaning the solute can more easily dissolve into it's components.
What three factors can speed up the rate of something dissolving?
Three factors that speed up the rate of dissolution are increased temperature, increased surface area, and stirring the mixture.
How does surface area of an object affect gravity?
increasing the surface area of reactants in a solid form the speed of reaction is increased the contact between the solid reactants or liquids and gas.
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 the earths radius and surface area increasing?
no
Why is a cell forced to divide?
it's the problem of surface area -to- volume ratio that mean there is no fitting between increasing of surface area and increasing of volume
