Why are some reagent bottle colored?
Reagent bottles are colored to protect light-sensitive chemicals or compounds from being degraded by exposure to light. The colored glass helps to block certain wavelengths of light that can cause chemical reactions or decomposition of the reagent inside the bottle.
Why anthrone reagent needs to be kept cold before using?
Anthrone reagent is prepared in concentrated sulfuric acid. Adding reagents to acid causes immediate dissociation of the reagent and releases heat. If your solution weren't cold, it could generate enough heat to blow out of the flask or bottle.
Why do the bottle filled with water do not melt when kept in fire?
Because the temperature of water can't normally go beyond 100 degree Celsius , because that is the temperature of boiling water. When we keep any bottle with water on fire, heat transmits from bottle to water and since the temperature of bottle and water should be almost same, the temperature of bottle does not go far beyond 100 degree Celsius. And since the melting point of the bottle(plastic) are in general above 100 degree Celcius they don't melt.
How is anthrone reagent stored?
Anthrone reagent should be stored in a tightly sealed container away from direct sunlight and heat sources, at room temperature. It should also be kept away from incompatible substances and moisture, and monitored for any signs of degradation or contamination before use.
Why ariated water bottle kept under water during summer?

Can acetone be kept in plastic bottle?
Acetone can be kept in a plastic bottle made from high-density polyethylene (HDPE) or polyethylene terephthalate (PET) since these materials are resistant to acetone. Avoid storing acetone in bottles made from other types of plastic, as it may cause the plastic to degrade and leak.
Why anthrone reagent needs to be kept cold before using?
Anthrone reagent is prepared in concentrated sulfuric acid. Adding reagents to acid causes immediate dissociation of the reagent and releases heat. If your solution weren't cold, it could generate enough heat to blow out of the flask or bottle.
Why is Bradford reagent kept in amber coloured bottles?
Bradford reagent is kept in amber-colored bottles to protect it from light exposure. Light can degrade the reagent, affecting its stability and performance. The amber color helps to block out light that can lead to decomposition of the reagent molecules, ensuring its reliability for accurate protein analysis.
Is water kept in plastic bottles suitable for drinking?
Are we talking water that has been bottled and distributed or are we talking about you filling up a bottle yourself? Bottled waters are filled under sanitary conditions. They should be pretty much okay as long as they remain sealed. Water stored in plastic can acquire some plastic taste to them. If they weren't filled under sanitary conditions, bacteria can build up and cause severe health problems.
What will happen if 20 ml of water is placed in a plastic airtight bottle which is kept in sunlight for sometime and then some smoke is inserted in the bottle and it is again closed airtight?
Well depends what gas you put in if it oxygen then it will evaporate but if it a gas which is flamable, it explode
