Preparing Oxalic Acid Solution Quiz

• Take a watch glass, wash it with distilled water and dry it.
• Weigh the exact amount of clean and dried watch glass and record its weight in the notebook.
• Weigh correctly on the watch glass 3.15 g of oxalic acid and record this weight in the notebook.
• Using a funnel, transfer oxalic acid softly and carefully from the watch glass into a clean and dry measuring flask.
• Wash the watch glass with distilled water to move the particles that stick to it into the foam with the assistance of a wash bottle.
• For this purpose, the volume of distilled water should not exceed 50 ml.
• Wash funnels several times with distilled water to move the sticking particles into the measuring flask using a wash bottle. Add water in tiny quantities while washing the funnel.
• Turn the flask of measurement until the oxalic acid dissolves.
• Add the last few mL of distilled water drop into the measuring flask until the reduced meniscus level just touches the mark.
• Put the stopper on the mouth of the flask and shake softly to make the entire solution uniform.

The oxalic acid solution has a Molarity of 10 and a weight of 3.15 g.

Test your knowledge of preparing oxalic acid solution through this quiz, which covers the process of accurately measuring the compound, transferring it to a measuring flask, and creating a uniform solution with a specific molarity and weight.
