Why acid is called as acid?
Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word acid is derived from the Latin acidus/acēre, meaning ‘sour’. Chemicals or substances having the property of an acid are said to be acidic.
Why is picric acid most acidic?
Of course picric acid is more acidic than phenol because of the presence of three nitro groups( which is a deactivating group) at o-,p- positions which makes it more acidic than phenol( carbolic acid) which has only one hydroxyl group.
Which acid is known as picric acid?
picric acid, also called 2,4,6-trinitrophenol, pale yellow, odourless crystalline solid that has been used as a military explosive, as a yellow dye, and as an antiseptic.
Why is picric acid so strong?
Picric acid has nitro groups in para and ortho positions, so it has great possibility to go for resonance, thus it is supposed to be a very good acid.
What is acid in short answer?
An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).
What is acid very short answer?
An acid is a chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts. Some acids burn or dissolve other substances that they come into contact with.
Why is phenol acidic than alcohol?
htm. Phenols are much more acidic than alcohols because the negative charge in the phenoxide ion is not localized on the oxygen atom, as it is in an alkoxide ion, but is delocalized-it is shared by a number of carbon atoms in the benzene ring.
What is the full form of TNT?
Trinitrotoluene
TNT/Full name
trinitrotoluene (TNT), a pale yellow, solid organic nitrogen compound used chiefly as an explosive, prepared by stepwise nitration of toluene.
How do you explain acid and base to a child?
A substance is acidic if it has a pH level of 0 through 7, where 0 is the most acidic. A substance is basic, then, if it has a pH level of 7 through 14, where 14 is the most basic. If a substance has a pH of exactly 7, it’s neutral. This means it has equal amounts of hydrogen and hydroxide ions.
