For example, Domino's Pizza, which has four outlets in New York, said its typical serving, which is two slices weighing a total of 5 1/4 ounces, has 344 calories and 9.5 grams of fat. Pizza Hut, a nationwide chain with outlets in New York City, said a 4.4-ounce slice has 253 calories and 9 grams of fat.
Buffer Definition: A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH.
Acid-base buffers confer resistance to a change in the pH of a solution when hydrogen ions (protons) or hydroxide ions are added or removed. An acid-base buffer typically consists of a weak acid, and its conjugate base (salt) (see Equations 2-4 in the blue box, below).t is possible to plot a titration curve for this buffer system, just as you did for your solution in the acid-base-equilibria experiment. In this plot, the vertical axis shows the pH of the buffered solution (in this case, the blood).
