You will learn all about solutions and their basic properties, including their freezing point and electrical conductivity. Discover a few ways to even make things dissolve faster.
After completing this tutorial, you will be able to complete the following:
How does the process of dissolution begin?
~ The dissolution process begins when particles of the solvent and solute start to collide with one another.
How does temperature affect the rate of dissolution?
~ Because increasing the temperature of the solvent increases the kinetic energy of its particles, more collisions between the particles of the solute and solvent occur. The more frequently these collisions take place, the faster the rate of dissolution.
What impact would increasing the surface area of a solvent have on the rate of dissolution?
~ Increasing the surface area of the a solvent increases the rate of dissolution because additional surface area allows for more collisions.
What would agitating a solution do to its rate of dissolution?
~ Agitating a solution helps to move the dissolved particles away from contact surfaces and onto the solvent surface more quickly. This also increases the rate of dissolution.
