摘要
介绍从花中提取色素制成酸碱指示剂的方法,测试了植物色素在不同pH值范围内的显色情况,并将自制植物酸碱指示剂进行浓缩用于几种常见盐溶液的显色指示,取得了满意的效果.
This paper introduced the method of preparing acid-alkali indicator with pigment extracted from flowers.The chromogenic circumstances of plant pigment were measured in different pH ranges.The self-made indicator was concentrated to indicate chromogenic circumstances of several common salt solutions.These experiments have gained satisfying effects.
