How can Phthalein test be identified?
(e) Phthalein Dye Test: Phenol on heating with phthalic anhydride in the presence of concentrated sulfuric acid forms a colourless condensation compound called phenolphthalein. On further reaction with dilute sodium hydroxide solution gives a pink colour fluorescent compound called fluorescein.
What does resorcinol do for the skin?
Resorcinol is used to treat acne, seborrheic dermatitis, eczema, psoriasis, and other skin disorders. It is also used to treat corns, calluses, and warts. Resorcinol works by helping to remove hard, scaly, or roughened skin. Some of these preparations are available only with your doctor’s prescription.
What is Phthalein reaction?
Phthalein dyes are a class of dyes mainly used as pH indicators, due to their ability to change colors depending on pH. They are formed by the reaction of phthalic anhydride with various phenols. They are a subclass of triarylmethane dyes.
Does oxalic acid respond to Phthalein test?
Answer: In sodium bicarbonate test use acid free alcohol so that it should not interfere with the functional group of the given organic compound. Dicarboxylic acids like oxalic acid, terephthalic acid and isophthalic acid do not give fluorescein test.
Who should not use resorcinol?
Resorcinol may be absorbed through the skin and should not be used on large areas of the bodies of infants and children. In addition, resorcinol should not be used on wounds, since doing so may cause a blood disease called methemoglobinemia.
What is Phenoxide ion?
A phenoxide ion is the conjugate base of phenol. Phenoxide is a conjugate base, this implies that it is formed from an acid that has given up its hydrogen. This acid is a phenol molecule. The hydrogen of the hydroxyl leaves, and an O− remains, forming the ‘oxide ion’ part of the phenoxide ion.
