Ferric chloride reacts with phenol to form a complex that absorbs light in the violet region of the spectrum. The violet color is due to this complex forming between the ferric ions and the phenol molecules, resulting in the absorption of light at specific wavelengths that appear as violet to the human eye.
What else can I help you with?
Is Feric chloride corrosive?
Yes, ferric chloride is corrosive. It can cause skin and eye irritation upon contact. It should be handled with care and proper protective equipment to prevent harm.
Why fused calcium chloride is used in the preparation of feric chloride?
Fused calcium chloride is used in the preparation of ferric chloride as a dehydrating agent. It helps to remove any water present in the reactants or products, ensuring the reaction proceeds efficiently. Additionally, fused calcium chloride can help to purify the ferric chloride product by absorbing impurities and moisture.
What is the name of the compound with the formula FeNO23?
The compound with the formula FeNO23 does not exist. The correct formula should have whole number subscripts for each element/ion, and in this case, it seems to be incorrectly written.
What is the mechanism of ferric chloride test?
The ferric chloride test is used to detect the presence of phenolic compounds in a substance. It involves adding ferric chloride solution to the sample, and if phenolic compounds are present, a colored complex forms due to the formation of iron-phenol complexes. The intensity of the color change can be used to estimate the concentration of phenolic compounds in the sample.
When was Zwonimir Feric born?
Zwonimir Feric was born in 1911.
Is Feric chloride corrosive?
Yes, ferric chloride is corrosive. It can cause skin and eye irritation upon contact. It should be handled with care and proper protective equipment to prevent harm.
When did Zwonimir Feric die?
Zwonimir Feric died on February 23, 1993.

What is the color formed when salicylaldehyde reacts with neutral ferric chloride?
When salicylaldehyde reacts with neutral ferric chloride, a complex known as ferric salicylaldehyde is formed. This complex typically appears as a deep purple color. The color change is due to the formation of a coordination compound between the salicylaldehyde and the ferric chloride, resulting in the absorption of certain wavelengths of light and the reflection of others, giving rise to the observed color.
What are oxides of magnetic materials?
feric oxid and ferrous cxides are the oxides of magnetic matrial
Why feric alum used as indicator?
Feric alum, or ferric ammonium sulfate, is used as an indicator because it forms a colored complex with base. The formation of this complex changes the color of the solution, making it useful for detecting the endpoint of an acid-base titration.
What is the name of the compound with the formula FeNO23?
The compound with the formula FeNO23 does not exist. The correct formula should have whole number subscripts for each element/ion, and in this case, it seems to be incorrectly written.
Formula for ferrous sulfate?
Ferrous is a derivative of the latin word Ferrum, for Iron. Which is why iron on the periodic table is Fe. Ferrous is iron in a +2 state, and feric is iron in a +3 State. Ferrous sulfate is just FeSO4
Is cement a mixture?
Yes, cement is a mixture of various materials such as limestone, clay, and gypsum that is ground into a fine powder. When mixed with water, cement forms a paste that hardens and binds together aggregates like sand and gravel to create concrete.
What is the ratio of Feric oxide and alumina in thermit reaction?
The ratio of iron(III) oxide (Fe2O3) to aluminum (Al) in a thermite reaction is typically 3:8. This balanced stoichiometric ratio ensures that a sufficient amount of aluminum is present to reduce the iron(III) oxide, resulting in a vigorous exothermic reaction that produces molten iron and aluminum oxide.
