“Tris” is short for tris(hydroxymethyl)aminomethane.This weak base is widely used in biochemical research forthe preparation of buffers. It offers low toxicity and a pKb(5.92 at 25°C) that is convenient for the control of pHin clinical applications. A buffer is prepared by mixing0.050 mol of tris with 0.025 mol of HCl in a volume of2.00 L. Compute the pH of the solution.
