good selectivity: ensures that other substances in the sample will not precipitate along with the analyte
dimethylglyoxime:a specific reagent that precipitates only Ni(II)
chelating agents:a chemical compound that coordinates with a metal to form a chelate, often used to trap or remove heavy metal ions
reducing agents:convert an analyte to its elemental form for weighing
organic agents:example of this are Nitron and Sodium tetraphenylborate
precipitants: other name for precipitating reagents
silver nitrate:from acidic solution, it precipitates Cl, Br, I and SCN
coordination compounds:slightly soluble ionic products
metal chelates:relatively non polar and have low solublility in water not not in organic liquids
precipitates:a substance precipitated from a solution
reagents:substance used to test the presence of a substance in a sample
chelates: are cylindrical metal-organic compounds
gravimetry: mass determination
specific reagents:react only with a single chemical species
selective reagents:react with a limited number of species
