Explain about Folic acid
Folic acid occurs as a yellow or orange-yellow, microcrystalline powder, almost without odour and taste. Water content of folic acid is up to 8.5%. Folic acid is very slightly soluble in water. Solubility increases with the temperature and the pH. Folic acid is sparingly soluble to insoluble in the usual organic solvents. The substance is without characteristic melting point, heating above 250°C will produce darkening and decomposition. Aqueous solutions of folic acid are not stable in the presence of reducing and oxidizing agents, heavy metal ions as well as sunlight and UV light.
