In chemistry, a "buffer" is a solution you add to another solution in order to balance its pH, its relative acidity or its alkalinity. You make a buffer using a "weak" acid or base and its "conjugate" base or acid, respectively. To determine a buffer's pH--or extrapolate from its ...

In Chemistry, you will often have to perform analyses of solutions. A solution consists of at least one solute dissolving in a solvent. Molality represents the amount of solute in the solvent. As the molality changes, it affects the boiling point and fre
