  红石蕊试纸的用处

  红石蕊试纸主要用于检测碱性溶液,试纸遇碱性变蓝

  性质:当pH值大于8.3时,试纸变蓝,小于8.3时,试纸不变色,故用红石蕊检测碱性溶液时是不能准备读出碱性pH值得读数;

  特点:遇到氧化性强的物质时,有可能褪色,保存时注意干燥避光;

  检测气体酸碱性,用石蕊试纸检测气体的酸碱性时,先将石蕊试纸用蒸馏水润湿,再将试纸悬于盛装气体或产生产生气体仪器口部,气体接触试纸后,会有颜色变化,从而判断气体的性质;

  保存:该试纸需保存在避光干燥处;

  红石蕊的使用方法

  步骤1:打开包装盒,呈现出的红色纸片为红石蕊试纸;

undefined

  步骤2:取一片红石蕊试纸,用新鲜的蒸馏水润湿;

undefined

  步骤3:将润湿的红石蕊试纸粘在玻璃棒上,接近被测气体的储气装置,观察试纸的颜色变化,判断气体的性质;
