What is the color of ferric chloride salt in water?
Ferric chloride gives green solution in waterReddish or yellowish
Is vanillin positive in a ferric chloride test?
Yes, vanillin is positive in a ferric chloride test. When vanillin reacts with ferric chloride, it forms a colored complex that gives a characteristic blue or green color, indicating the presence of phenolic compounds.
What is difference between feeric alum and non ferric alum?
Ferric alum contains iron, which gives it a yellow color, while non-ferric alum does not contain iron and is typically colorless. Ferric alum is commonly used in water purification and wastewater treatment processes, while non-ferric alum is used in industries like paper manufacturing and tanning.
What is the oxidation state for ferrous chloride?
The name gives the clue. If any chemical is described as '-ous' it has the lower oxidation state. If described as '-ic' , it has the higher oxidation state, Hence Ferrous chloride is 'Iron(II) chloride' ( FeCl2) Ferric chloride is 'Iron(III) chloride' ( FeCl3). Similarly with Nitric Acid and Nitrous Acid ( HNO3/HNO2) Sulphuric acid and Sulphurous Acid (H2SO4/H2SO3)
What is the colour of ferrous ion?
yellowIron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl2.FeCl2 crystallizes from water as the greenish tetrahydrate, aqueous solutions of FeCl2 are yellow.

How ferric chloride is formed?
Ferric chloride is formed by the reaction of iron with chlorine gas, resulting in the formation of iron(III) chloride. This reaction can also be achieved by dissolving iron in hydrochloric acid. The chemical formula for ferric chloride is FeCl3.
Why normal ferric chloride is not used in detection of phenol?
Normal ferric chloride gives a positive test for phenol as it forms a violet complex with it. This can lead to false positives in other compounds that also react with ferric chloride, making it unreliable for detecting phenol specifically. Instead, a modified version called FeCl3/KI reagent is commonly used for phenol detection as it gives a distinct green color with phenol, allowing for more accurate and specific results.
Why aspirin gives voilet clr with ferric chloride?
Ferric chloride, or iron(III) chloride will not react with aspirin. It will, however, react with salicylic acid, which is used to synthesize aspirin. In this light, adding an aqueous ferric chloride solution to a sample of aspirin is a good way to see if there is any unreacted salicylic acid. A purple color is an indication of salicylic acid. A sample of pure aspirin should not exhibit any color change.
Benzoic acid gives an orange colouration with neutral ferric chloride. What is the reason for that?
Well, sugar, the reason for that orange coloration is due to the formation of a complex between benzoic acid and ferric chloride. This complex absorbs light in the visible spectrum, giving it that lovely orange hue. So, next time you see that color, just remember it's all about that chemical bonding, honey.
Which compound give brown precipitate with alkaline potassium per mangnate solution?
Ferrous chloride in presence of hydrochloric acid gives brown precipitates of Ferric chloride with potassium permanganate.
Hydrolysis of ester ethyl ethanoate gives what?
Hydrolysis of ester ethyl ethanoate (or ethyl acetate) results in the formation of acetic acid and ethanol. This reaction involves breaking the ester bond through the addition of water, leading to the formation of the corresponding carboxylic acid and alcohol.
What is difference between feeric alum and non ferric alum?
Ferric alum contains iron, which gives it a yellow color, while non-ferric alum does not contain iron and is typically colorless. Ferric alum is commonly used in water purification and wastewater treatment processes, while non-ferric alum is used in industries like paper manufacturing and tanning.
Who gives oxygen atom in ester synthesis?
It depends on which reaction is used to create the ester. When catalyzing a carboxylic acid with a strong base such as NaOH, then using an alkyl halide, the oxygen is from the acid. R-COOacidH + NaOH -> R-COO-acid + R'X ->R-COOacidR' When using a carboxylic acid with an alcohol or an acid chloride with an alcohol, the oxygen originates from the alcohol. R-COOacidH + R'OalcoholH + HCl -> R-COOalcoholR' R-COOacidCl + R'OalcoholH + Pyridine -> R-COOalcoholR'
What is the oxidation state for ferrous chloride?

What gives out lithium chloride pluse water?
This is a lithium chloride water solution containing ions Cl- and Li+.
