pH及缓冲溶液(pH and Buffer solution).pH及緩衝溶液(pHandBuffersolution)學習目標 何謂pH值，學習溶液之pH值計算。認識緩衝溶液，瞭解緩衝溶液緩衝能力的決定因子。學習緩衝溶液組成物質的pKa值與緩衝溶液pH值間的關 係與計算。學習pHmeter(酸鹼測定儀)的操作。能以pHmeter(酸鹼測定儀)作出單一...
缓冲液(Buffer solution)通常是由「弱酸及其共轭碱」或「弱碱及其共轭酸」缓冲对所组成的溶液,能够在加入一定量其他物质时减缓pH的改变。以生物实验中最常用的一种缓冲液PBS为例,是由Na2HPO4、KH2PO4组成的缓冲对,在PH5.8-8.0范围内有较强的缓冲能力。
