Indicate the option that is true:(1). An indicator electrode has an upper limit of measurement; That is, it does not serve as a precise analytical instrument when the concentrations of the analyte are very high.(2). Some electrodes take a long time to respond, but that is usually not an insurmountable drawback.(3). The representation of the potential of an indicator electrode against the analyte concentration is a straight line for analyte concentrations below a certain value.(4). For activities lower than the lower detection limit, the electrode always measures the same potential.
