Middle oil of coal-tar distillation comprise naphthalene and phenolic elements. Phenolic compounds are isolated in subsequent steps.
Step a: Middle oil is washed along with H2SO4. It dissolves basic impurities such as pyridine (base).
Step b: Extreme cooling separates naphthalene (a low melting solid)
Step c: Filtrate of step b is treated with aqueous NaOH when phenols dissolve as phenoxides. Carbon dioxide is then given by the solution to liberate phenols.
Step d: Crude phenol (of step c) is subjected to fractional distillation.
Write down the reactions taking place in different zones in the blast furnace during the extraction of iron.
We performed a titration in the lab with mock gastric juice and potassium hydroxide. We titrated to end point and then to another colour change and noted both the volumes. We are n

Q. Define Ionisation Isomerism? Ionisation Isomerism: when coordinated ions exchange positions with ions present in the lattice position, we get ionisation isomers. Thus comp
Tempering is a heat treatment method for metals and alloys. In steels, tempering is completed to "toughen" the metal by transforming brittle marten site into bainite or a combinat
