#When will a precipitate form how to#

How to tell if a yellow precipitate is SnS 2 or has CdS as well Therefore, barium carbonate, barium sulfate and barium sulfite are white precipitates. Which anion will form a precipitate with Ba2+?Д«a 2+ ion form precipitates with anions such as sulfate, sulfite and carbonate. Questions asked by students Ask your question and find the answer free. That means, there are no precipitates of nitrate compounds. So when anion vary, color of preciptate also vary.Дoes nitrate ion form precipitates with cations?ДЄll 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 theirДЄccoring to the anion or cation, colour can be vary.ДЄccording to the cation Ferrous chloride and Ferric chlorideД¬hloride ion (anion) is common for both compounds. Ksp value give a very clear clarification about precipitationДЄccording to the ksp value, we can decide whether a solid will be precipitated or not.Д«ut, 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.ДЄll alkaline earth metals forms insoluble carbonate. We study deeply about solubility of metal carbonates, most of the carbonates are insoluble in water.ДЇrom alkali metals, only lithium forms insoluble carbonate.

Now we consider about those precipitate of anions and those precipitates colours.Д¬arbonates have a variation because there are soluble and insoluble carbonates. Metal sulfide are not soluble and they have different colours too.Д¬arbonate, 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 hydroxidesД¬hromium 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 precipitatesД¬aCO 3, MgCO 3, SrCO 3 are precipitates and they are white.Alkaline earth metals forms both precipitates and solutions.
