1.	While using reference electrodes, the internal liquid level should always be kept above that of the sample solution.(a) True(b) FalseThe question was asked by my school principal while I was bunking the class.Enquiry is from Secondary Reference Electrodes in section pH Meters and Ion Analysers of Analytical Instrumentation
Answer» The correct option is (a) True To explain I would say: While USING reference electrodes, the internal LIQUID level should always be KEPT above that of the sample solution. This is done to prevent contamination of the electrolyte solution.
