1.	Sodium selective electrode provides a good response in measurement when the pH is above which of the following values?(a) 2(b) 3(c) 5(d) 10The question was posed to me during an interview for a job.I want to ask this question from Sodium Analyser in chapter Dissolved Component Analysers of Analytical Instrumentation
Answer» CORRECT answer is (d) 10 For explanation: Sodium selective ELECTRODE provides a good response in measurement when the pH of the solution is above 10. Hence, the BUFFER solution is USED.
