This is summarised in the table below. Metal Ion. clearlydev downWeb1. First, despite their name, many of them are not entirely ion-specific. For example, the sodium electrode you will use also responds to potassium ions, although not with the same sensitivity. This means that Na+ will be overestimated if a high concentration of K+ is present. Mathematical techniques have been devised to compensate for this. 2. blue ridge georgia 10 day forecastWebIn flame tests, sodium ions may contaminate a sample and produce a yellow flame, masking the colors of the other ions.
