Ascorbic acid is a highly  flammable solid and therefore should be stored away from heat sources. It can cause serious eye irritation so appropriate eye protection must be worn in the lab. It has a molecular weight of 176.14 g mol-1 and is soluble in water, with a solubility of  Blank 6 Question 2 g/100 mL. In the pure state at room temperature, it is a  Blank 7 Question 2 .

Ascorbic acid (CAS No 50-81-7), also known as Vitamin C , is well known as an antioxidant in foodstuffs i.e. it acts as an oxidising agent.

A standard containing ascorbic acid (25.0 mg mL-1) was analysed using reversed-phase HPLC with UV detection at 250 nm, giving a peak area of 34210.  A sample containing ascorbic acid was then analysed under the same conditions, giving a peak area of 31622.  Determine the concentration of ascorbic acid in the sample (in mg mL-1).

Water soluble, energy giving vitamin that is also known as "Ascorbic Acid"

Calculate the mass of ascorbic acid (Molar mass = 176 g mol–1) to be dissolved in 75 g ofacetic acid, to lower its freezing point by 1·5°C.(Kf = 3·9 K kg mol–1)
