Why do we use dark-colored reagent bottles in storing some chemicals?

Under the action of light, nitric acid slowly decomposes into oxides of nitrogen plus free oxygen, and may thus produce a pressure in a stoppered container. If kept for any time, the stopper should be occasionally loosened (carefully) to avoid pressure build up.

Why using dark colored reagent bottles in storing in storing some chemicals?

What is an appropriate step to take if you are storing incompatible chemicals?
An appropriate step to take when storing incompatible chemicals is to keep the chemicals stored in different locations. For example, bleach and ammonia need to be stored some distance away from each other.
Storing toxic chemicals in metal drums is unwise because?
They corrode.
Purpose of moistened filter paper in a Petri dish?
Using a piece of paper when transferring solid chemicals into a test tube? 2. Using a dark colored reagent bottles in storing chemicals. 3. Using a dry and clean spatula when taking small amounts of solid from a reagent bottle. 4. Never pouring water into acid. 5. not clamping glassware too tightly 6. Moistening the filter paper before placing it in the funnel. 7. using a glass rod when pouring a liquid into a narrow mouthed container like test tube and Erlenmeyer flask. please answer even just one question. THANK YOU.
Why is glass a good substances for storing chemicals?
Glass is unreactive with most chemicals. It is also very stable - not deforming, melting, or degrading with time. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 /°C at 20°C), making them resistant to thermal shock, more so than any other common glass. Such glass is less subject to thermal stress and is commonly used for the construction of reagent bottles. Glass also tends to be clear, which makes it easier to determine what is inside the container. There are some chemicals that cannot be stored in glass because the react with it - such as hydrofluoric acid. Other chemicals are not stored in glass because as they decompose, they release gasses that can build up in pressure to the point that they will burst the container. Of course glass does not usually have enough tensile strength to contain gases under pressure. Some chemicals are photoreactive - i.e. they decompose, polymerize or otherwise react when exposed to light. Since most glass is clear, such chemicals are usually better stored in opaque containers.

Using dark-colored reagent bottles in storing some chemicals?
This amber/brown color is one of many pigments that are used to prevent ultraviolet (UV) light from penetrating the chemical reagent's bottle and damaging a photosensitive chemical. While there are some molecules that are affected (often very little) by the visible spectrum of colored light, UV-light is the primary range of the electromagnetic spectrum that can catalyze unwanted reactions in bottles which effectively degrades the reagent.
What type of bottle is used for storing acids and bases?
A Reagent Bottle.
