To prepare an ascorbic acid solution, first, determine the desired concentration and volume. Weigh the appropriate amount of ascorbic acid (vitamin C) using a balance, typically around 1 gram for a 100 mL solution at a concentration of 1% (w/v). Dissolve the ascorbic acid in distilled water by stirring until fully dissolved, then transfer the solution to a volumetric flask or graduated cylinder, adding water to reach the desired final volume. Store the solution in a dark container at low temperatures to minimize degradation.
The acid that reduces Fehling's solution is ascorbic acid (vitamin C). It causes the blue solution to turn into a brick-red precipitate of cuprous oxide.
To prepare a 50mm glucose solution, you would need to dissolve 9g of glucose in enough water to make 100mL of solution. This would give you a solution with a concentration of 50mm (millimolar).
Ascorbic acid is not volatile.
To prepare a chitosan solution, dissolve chitosan powder in an acidic solution (such as acetic acid or hydrochloric acid) with stirring. Adjust the pH as needed and filter the solution to remove any undissolved particles. The concentration of the chitosan solution can be adjusted by varying the amount of chitosan powder used.
it is very easy to prepare working solution from a stock solution we use the formula for this purpose which is: C1V1 = C2V2 C1 is the concentration of the stock solution V1 required volume from the stock solution C2 concentration of the working solution V2 volume of the working solution
To prepare an ascorbic acid solution, dissolve the appropriate amount of ascorbic acid powder in distilled water. Stir the solution until the powder is completely dissolved. Ensure the solution is properly mixed and then store it in a clean container.
Ascorbic acid is sensitive to air and can undergo oxidation when exposed, leading to a loss of its antioxidant properties and potential breakdown of the compound. This oxidation reaction can reduce the effectiveness of the ascorbic acid solution.
Yes, ascorbic acid (vitamin C) is an acidic compound and can lower the pH of a solution when added.
You can determine that the ascorbic acid is gone from the solution by observing a color change in the reaction mixture. Initially, the iodine will react with the ascorbic acid to form a colorless iodide ion. Once all the ascorbic acid is consumed, any excess iodine will turn the solution brown due to the formation of triiodide ions.
The question is unanswerable without knowing the concentration as well.

The acid that reduces Fehling's solution is ascorbic acid (vitamin C). It causes the blue solution to turn into a brick-red precipitate of cuprous oxide.
Ascorbic Acid is the chemical name for Vitamin C.
To prepare a 0.01N KBr solution, dissolve 0.74g of KBr in 1 liter of water. This will give you a solution with a molarity of 0.01N for KBr.
See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution.
To prepare a buffer solution which may be acidic. Titrate ethanoic acid (weak acid) with sodium ethanoate(salt).
To prepare a 0.5M glutaraldehyde solution, you would need to dilute a concentrated glutaraldehyde stock solution with the appropriate volume of water or buffer solution. Calculate the volume of stock solution needed based on the desired final volume and concentration, then dilute with the solvent. Finally, mix the solution thoroughly to ensure uniform distribution. Remember to follow safety protocols when working with glutaraldehyde, as it is a hazardous chemical.
