Oxalic acid (COOH) .2H O is to be dissolved in one litre of distilled water to get N/10 oxalic 2 2 acid solution. Procedure Weigh accurately 6.3 g (COOH) .2H O and transfer it to a volumetric flask (1 litre), half-filled 2 2 with distilled water. Shake well and make the volume up to the mark. Label it as N/10 oxalic acid solution. Note: If ... Divide the normality by 2 to get molarity of oxalic acid. If the solution is about to be made then find the mole number of oxalic acid. Molecule weight of hydrated oxalic acid ( C O O H) 2 .2 H 2 O is 126. Mole number, m = weight taken ÷ 126. The volume is 250 ml, 1/4 of 1000 ml, so molarity = m×4.

Equivalent Weight of Oxalic Acid (Calculation) The molar mass of oxalic acid is 126 grams per mole. Since the chemical formula of this compound can be written as COOH-COOH, it can be understood that oxalic acid is a dibasic acid which has the ability to donate two H + ions. Therefore, the equivalent weight of oxalic acid can be calculated with the help of the following formula:

Calculate amount of oxalic acid used To prepare 100 ml of 0.1 solutionhi tammana you did not mentioned that it is 0.1N or 0.1M but i will explain you both for m
Oxalic acid (H2C2O4) is a relatively strong organic acid and is a common reducing agent in organic chemistry. There are a number of methods for preparing oxalic acid from nitric acid, and one important difference among them is the amount of oxalic acid that is produced from a given amount of nitric acid.

The molecular weight of a monoprotic acid HX was to be de¬termined. A sample of 15.126 grams of HX was dis¬solved in distilled water and the volume brought to ex¬actly 250.00 millilitres in a volumetric flask. Several 50.00 millilitre por¬tions of this solution were titrated against NaOH solution, re¬quiring an average of 38.21 millilitres of NaOH.
