Titration with EDTA is used to measure nitrates in water. Colorimetry and spectroscopic methods are important techniques in chemical analysis.
The method used to measure the presence of nitrates in water is Titration with EDTA. This method involves adding a titrant solution containing EDTA (ethylenediaminetetraacetic acid) to the water sample until the endpoint is reached, indicated by a color change.
Colorimetry is a technique commonly used in chemical analysis, where the amount of a substance is determined by measuring the absorbance of visible light by a colored product formed in a reaction.
Spectroscopic methods involve analyzing the interaction between electromagnetic radiation and matter to determine the concentration of substances in a sample, as seen in Nessler's method for ammonia determination.
