How can we detect nitrates

WebInorganic Nitrates and Nitrites. Inorganic nitrate (NO 3 -) and nitrite (NO 2 -) are water soluble (as a result of their interaction with the positively charged portions of polar water molecules) ( Figure 1) and commonly exist as salts of nitric acid and nitrous acid, respectively. They are often bound to a metal cation such as Na+ or K+ and ... The nitrate ion can easily be identified by heating copper turnings along with concentrated sulfuric acid. Effervescence of a brown, pungent gas is observed which turns moist blue litmus paper red. Here sulfuric acid reacts with the nitrate ion to form nitric acid.
