For 10 points, name these solutions that resist changes to pH.
Phosphate serves this role in a salt solution used to culture cells called P-B-S. One of these substances is produced by reacting ethylene oxide and glycine, and is named bicine ["BYE-seen"]. A set of twelve of these substances commonly used in biological research were described by Norman Good. Bicarbonate serves this role in blood. The Henderson-Hasselbalch equation is useful for finding pH of these systems. These solutions have their largest capacity when their pH equals their pKa. One of these solutions can be made by mixing a weak acid with its conjugate base. For 10 points, name these solutions that resist changes to pH.
