The Standard Curve

When doing biological experiments, it is essential that the exact concentration of every solution be known. It is also important to know the pH of a solution since this is often critical in biological reactions. Buffered solutions, which can absorb minor perturbations to pH, are often used to maintain the pH of a solution. Different ways of describing the concentration of a solution as well as pH and buffers are reviewed below:
