FAQs
What is the difference between citric acid anhydrous and monohydrate?
Citric acid anhydrous contains no water molecules in its crystal structure, while the monohydrate form contains one water molecule per citric acid molecule. The anhydrous form is preferred for applications requiring precise molecular weight calculations.
Can this citric acid be used in food applications?
Yes, this Merck-grade citric acid meets food-grade standards and is suitable for use as an acidulant and preservative in food and beverage products.
What is the shelf life of citric acid anhydrous?
When stored properly in a cool, dry place with the container tightly sealed, citric acid anhydrous has an indefinite shelf life.
How should I dispose of unused citric acid?
Citric acid can be disposed of with regular laboratory waste. For large quantities, follow your institution’s chemical waste disposal procedures.
Is this product suitable for pH buffer preparation?
Absolutely. Citric acid is commonly used in combination with its sodium salts to prepare buffer solutions in the pH range of 3-6.
