Buffer solution example
WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion … WebBuffer solutions are therefore very useful in a wide variety of applications in which a relatively stable pH is required. A buffer may also be called a pH buffer, hydrogen ion buffer, or buffer solution. For example, blood contains natural buffers to maintain a stable pH of between 7.35 and 7.45 so that our enzymes work correctly.
