香蕉花苞叶提取物在简单的滴定中的应用技术作为一个指标
作者(年代):Satish Kolte春晚的故事花青素的提取化合物从香蕉花苞片(穆萨acuminata)成功地开展。香蕉的后代被磨与水混合。研磨混合物过滤后用棉布即X1。与甲醇残留动摇了好几次,黄色的液体是X2。都是用作指标在不同酸碱滴定。X1和X2含有花青素的导数负责它的使用作为一个指标。发现X1不是那么有效X2作为中和反应的指标。X2显示一个遥远的红色在酸性介质和遥远的绿色在碱性介质。X2显示类似的结果酚酞和甲基橙在酸碱滴定。复制这些滴定进行确认结果。 Different concentrations of the indicator as well as varying concentration of the titrant and titer were used to check for the application of indicator. The experiment was repeated for different neutralization reactions like: 1. Strong acid versus Strong base 2. Strong acid versus Weak base 3. Weak acid versus Strong base. The R.S.D and C.V. was calculated for all the types of titrations. The method proved analytically valid hence, effect of using such natural extracts as indicators for volumetric quantitative analysis as compared with conventional indicators is possible with good agreement.
