常用PH缓冲溶液CommonpHBufferSolutions在化学中,有一类能够减缓因外加强酸或强碱以及稀释等而引起的pH急剧变化的作用的溶液,此种溶液被称为pH缓冲溶液。pH缓冲溶液一般都是由浓度较大的弱酸及其共轭碱所组成,如HAc-Ac-,NH4+-NH3等,此种缓冲溶液具有抗外加强酸强碱的作用,同时还有抗稀释的作用。在高浓度的强酸或强...
Buffer solutions are composed of weak acids and bases that make them comparatively resistant to pH change. Theoretically buffers offer a ready source of both acid and base to either provide additional H+ if process consumes H+ or combine with excess H+ if a reaction generates acid....
