In a particular analysis the selectivity coefficeint K,A,I is 0.816. When a standad sample known to contain an anaylyte to interferent ratio of 5:1 is carried through the analysis, the error in determining the analyte is +6.3%. (a) Determine the appartent recovery for the analyte if R1=0. (b) deter,ome the apparent recovery for the interferent if Ra=1.
