HCOOH
What type of compound is CH3COOH?
Choose those compounds from the following which can turn blue litmus solution red:
HCHO, CH3COOH, CH3OH, C2H5OH, HCOOH, CH3CHO

Fill in the blank with appropriate word/words.
Vinegar is a solution of about ________per cent ________in water.
Assertion (A): Esterification is a process in which a sweet-smelling substance is produced.
Reason (R): When esters react with sodium hydroxide an alcohol and sodium salt of carboxylic acid are obtained.
A spatula full of sodium carbonate is taken in a test tube and 2 mL of dilute ethanoic acid is added to it.
