Question

describe the procedure for preparation of 1 normal oxalic acid

Answer 1

mole of oxalic acid means molecular weight gram of acid(90 g = 1 mol ). If you dissolve 90 g of acid in 1 liter of water then it will be 1 normal (N). To make 0.1 N you need to dissolve 9 g ofoxalic acid in 1 liter. If you want to make 1 Molar acid you should dissolve 90 g of acid in 1 kg of water.
