Q. How does one create oxalic acid at home?

Answer

Follow the steps: Get some distilled water and clean and dry a watch glass. Get a scale clean and dry some watch glass and record the weight of that amount. 3.15 grams of oxalic acid should be accurately measured using a watch glass and recorded in the lab notebook. Slowly and carefully transfer the oxalic acid from the watch glass to the dry volumetric cylinder. With the use of a wash bottle remove any debris from the watch glass by washing it with distilled water to let the particles clinging to the glass dissolve into the foam. The maximum amount of distilled water that should be used for this purpose is 50 ml. Any debris caught in a funnel can be easily removed by rinsing it several times with distilled water before being poured into a 100ml beaker. Slowly add a small amount of water while washing the funnel. As little as 50 mL of distilled water is all that's needed for this. Carefully rinse the funnel with distilled water from a wash bottle before using it to transfer the solution from the vial to the measuring flask. Spinning the measuring flask will help the oxalic acid dissolve.
