Which of the following are used to free bound ions or liberate bound i

1.	Which of the following are used to free bound ions or liberate bound ions?(a) Colouring agents(b) Ammonia Buffer(c) Reagents(d) Iodine solutionI had been asked this question at a job interview.This is a very interesting question from Sodium Analyser in section Dissolved Component Analysers of Analytical Instrumentation
Answer» RIGHT choice is (c) Reagents To EXPLAIN: Reagents are used to free bound ions or liberate bound ions. The ADDITION of reagent prevents unwanted ions from entering into the MEASUREMENT.
