Verifying Vitamin C in Product: pH Check

Question

I received a product containing Vitamin C (L-Ascorbic Acid). I would like to know: Is the Vitamin C already mixed into the product? How can I verify its presence? What should the pH of the product be if Vitamin C is present?

Based on the staff's reply, the Vitamin C is already mixed in the bottle you received.
The staff mentioned that you can easily check this by measuring the pH of the solution. If Vitamin C is present, the pH should be around 3 +/- 0.5.
