![]() That means, there are no precipitates of nitrate compounds. So when anion vary, color of preciptate also vary.ĭoes nitrate ion form precipitates with cations?Īll nitrate compounds are soluble in water. PbI 2 is yellow colour precipitate and PbCl 2 is white precipitate. Ferric chloride - (FeCl 3) - brown or colour.Ferrous chloride (FeCl 2) - colourless or green.We mainly present you a list of precipitates and theirĪccoring to the anion or cation, colour can be vary.Īccording to the cation Ferrous chloride and Ferric chlorideĬhloride ion (anion) is common for both compounds. Ksp value give a very clear clarification about precipitationĪccording to the ksp value, we can decide whether a solid will be precipitated or not.īut, here we don't focus on ksp value. FeCO 3 - white Identify carbonate ion in compounds - qualitative analysis.Now we list precipitates of carbonate ion with their colours. Also, all 3d metal cations' carbonates are insoluble in water. Li 2CO 3 is a white solid precipitate compound.Īll alkaline earth metals forms insoluble carbonate. We study deeply about solubility of metal carbonates, most of the carbonates are insoluble in water.įrom alkali metals, only lithium forms insoluble carbonate. Now we consider about those precipitate of anions and those precipitates colours.Ĭarbonates have a variation because there are soluble and insoluble carbonates. Metal sulfide are not soluble and they have different colours too.Ĭarbonate, sulfate, sulphite, phosphate, sulfide, chloride, bromide, iodide and more anions form precipitates with some metal ions. Precipitates of sulfides of 3d metals, d block metals and p block metal cations Precipitates list of 3d metals hydroxidesĬhromium hydroxide ( Cr(OH) 3 ) is dissolved when excess NaOH is added and give green colour solution. Below, we are listing precipitates of 3d metals with their colours according to the anion. Therefore we can use their precipitates colours to identify 3d metal ions. Most of 3d block metals precipitates show colours. Beryllium hydroxide ( Be(OH) 2 ) is an amphoteric hydroxide compound. When they are added to water, they are converted to their hydroxides. Sr(OH) 2 and Ba(OH) 2 are readily soluble and they are strong alkalis. Be(OH) 2, Mg(OH) 2 are insoluble in water.SrSO 4, BaSO 4 are white colour precipitates.All carbonates (CO 3 2-) of alkali earth metal ions are precipitatesĬaCO 3, MgCO 3, SrCO 3 are precipitates and they are white.Educators earn digital badges that certify knowledge, skill, and experience.Alkaline earth metals forms both precipitates and solutions.
