A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic flame emission spectrum (which may be affected by the presence of chloride ion). The color of flames in general also depends on temperature and oxygen fed; see flame color. WebJun 23, 2024 · A substance which gives brick red flame and breaks down on heating to give oxygen and brown gas is (a) Magnesium nitrate (b) Calcium nitrate (c) Barium nitrate (d) Strontium nitrate Sol: ( b) 2Ca (N0 3) 2 →2CaO + 4N0 2 + 0 2 N0 2 is a brown gas. Ca 2+ imparts brick red colour to the flame. WebAs an example, most of the aqueous sodium compounds are colorless while sodium +1 ion gives yellow color to the flame test. Colors of s block cations. In the s block there are two groups; group 1 and group 2. Group 1 cations: Group 1 (alkali metals) elements form only +1 ion. Group 2 cations: Group 2 (alkaline earth metals) elements form only ... can bamboo spoons go in the dishwasher
