Chromium flame test
WebNichrome is an alloy of nickel and chromium that does not react with hydrochloric acid. A platinum wire can be used instead because platinum is a highly inert metal, but it tends to be the more expensive option. ... Flame tests are usually not used to analyze mixtures of compounds because the flames of different elements can interfere with each ... WebA flame test is done by holding a sample of your compound on a piece of wire in a Bunsen flame. Ideally the wire is made of platinum because that doesn't itself give any colour to the flame. But normally in a school lab, you will probably be using nichrome wire - an alloy of nickel and chromium.
