A colourless liquid is tested with silver nitrate solution and produces a white precipitate and produces a brick red flame test result. Name the compound found in the colourless liquid
The silver nitrate test is a test for halide ions and the flame test is a test for metal ions, since they produced positive results you have an ionic substance. The result of a white precipitate is the positive result of the presence of chloride ions, and the result of a brick red flame in the flame test is a positive result for calcium ions. Therefore it is very likely that the compound in the colourless liquid is calcium chloride.
