BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following

佛与牛粪 传说有一次苏东坡拜访高僧佛印，两个人正谈的兴起，苏东坡突然披上佛印的袈裟问：“你看我像什么？” 佛印答：“像佛。”，然后问苏东坡：“你看老朽像什么？” 苏东坡正得意忘形，便大笑着说：“我看你像一滩牛粪！” 佛印笑了笑不再言语。 事后，苏东坡在得意之余，将此事告诉了苏小妹。不料苏小妹却兜头给他泼了一瓢冷水，“这下你可输惨了”，苏小妹说。苏东坡不解，问：“此话怎讲？”苏小妹答：“心中有何事物就看到何事物，佛印心中有佛，所以看你就是佛;而你心中有污秽之物，你看到的自然就是牛粪。” There is a legend about a time Su Dongpo visited the Zen master Foyin. Both of them were on the rise‚ Su Dongpo suddenly put on Foyin’s Buddha cassock and asked: "what do you think I am?" Foyin answered: “Like a Buddha.”
