Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

How can the number of effective collisions be increased? OAdd more water because then there will be more room for the molecules to get oriented correctly. Be sure you are mixing two solids, because then the particles will have more kinetic energy. Lower the temperature because that way the collision will last longer. Increase the total number of collisions.
