There are multiple way to measure the pH-Value of an solution. With a litmus paper it is easy to get a pretty precise pH-Value. The color indicates the value. If you need a more precise value you can for example use a pH-Meter which is using the conductivity of a solution.
有很多种办法测试溶液的PH值。应用石蕊试纸可以轻易地到一个精确的PH值。试纸的颜色指示了这个值。如果您需要一个更精确的值,您可以使用PH计,它采用的是通过PH电极测量溶液的电导率,并折算出PH值的方法。
