Does picric acid give effervescence with nahco3?
Since any acid stronger than carbonic acid can react with $NaHC{O_3}$ and give effervescence of $C{O_2}$. Hence, picric acid reacts with sodium bicarbonate to give effervescence of carbon dioxide while phenol does not.
What does picric acid react with?
Picric acid can react vigorously with oxidizing materials, and it can form unstable salts with concrete, ammonia, bases, and metals.
Why is picric acid a strong acid?
Due to electron withdrawing nature of —NO2 groups, picric acid becomes stronger acid than phenol.
Which compound does not give effervescence with NaHCO3?
Which among the following compounds will not give effervescence with sodium bicarbonate? Phenol does not react with NaHCO3 or NaCO3.
What is the acid used in the preparation of explosives?
nitric acid
The nitric acid is prepared in large buildings, in which are ranged long rows of retorts bricked up like ovens. These retorts are charged with sulphuric acid and nitrate of soda, and immediately the two compounds come into contact a chemical action commences, the nitric acid being released as a corrosive gas.
What makes a compound more acidic?
The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is. Look at the strengths in the bonds between the molecules in the ion. The more lopsided it is throughout the molecule, the stronger the acid. A molecule with a triple bond is more acidic than one that only has single bonds.
