Ascorbic acid is a naiturally occurrin organic compound wi antioxidant properties. It is a white solit, but impur samples can appear yellaeish. It dissolves well in watter tae gie mildly acidic solutions. Ascorbic acid is ane form ("vitamer") o vitamin C. It wis originally cried L-hexuronic acid, but, when it was foond tae hae vitamin C activity in ainimals ("vitamin C" bein defined as a vitamin activity, nae then a speceefic substance), the suggestion wis made tae rename it.
