时钟反应的终点,一般用显色剂出现颜色指示。本文探讨HCHO-HSO_3~-SO_3~(2-)系列受酸催化形成缔合型离子的pH突跃,作为HSO_3~-定量的分析依据。
The end of the clock reaction, the general use of color agents appear color indicator. In this paper, the pH jump of HCHO-HSO_3 ~ -SO_3 ~ (2-) series acid-catalyzed formation of associated ions was investigated as a basis for the quantitative analysis of HSO_3 ~ -.
