A solution of formic acid (HCOOH) has a pH of 2.53. Explain how many grams of formic acid are there in a 100mL of the solution?
Both the amide ion (NH2-) and the nitride ion(N3-) are stronger bases than the hyroxideion as well as hence do not exist in aqueous solutions. a). State the equations showing the reactions of these ions with water, and identify the bronsted acid and base in each case. b) Which of the two is the stronger base?
Suggest an experimental procedure that could be used to synthesize 1,2-dimethylcyclopentene from1,2-dimethylcyclopentanol. Explain how you might exploit the differences in the boiling points of the reactant and product in designing your experiment..
