Expert Answer:
Pure nitric acid is unstable to heat or sunlight. In the presence of sunlight, it decomposes even at room temperature.
Nitric acid stored in a bottle turns yellow. This colour is due to dissolved NO2 in HNO3. To avoid decomposition, nitric acid is normally stored in coloured bottles.
