During the formation of Grignard's reagent dry or anhydrous ether is used to prevent the magnesium from moisture because in presence of water magnesium leaves the organic material and combines with water.

Why biuret reagent only kept in plastic bottle?
sodium hydroxide attacks the glass
Why are some reagent bottle colored?
Some solvent or chemicals are sensitive to light, and they get oxidised when they are exposed to it.
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.
What are the adavantages of using ether as an extraction solvent?
The major disadvantage of using ether as an extracting solvent is that it is very flammable. It also oxidizes into an explosive in some cases, is an anesthetic, and is very vapor dense (meaning it will fall to the floor and move around there).
Why is silver nitrade always kept in brown glass bottles?
because it can decompose quickly if kept in transparent bottles
Why is a water bath used in grignard reagent?
Because the reaction is a strongly exothermic process. An ice bath should be kept readily available in case it should become necessary to cool the mixture to keep the reaction under control.
Why is Bradford reagent kept in amber coloured bottles?
Because it is unstable after it hit light.

Advantages of using ether as an extracting solvent?
Some reactions produce both nonpolar products and nonpolar sideproducts. If the product precipitates in ether (because of its poor solubility) and the side products are not, then the ether can be added to the product-sideproduct mixture and filtered out. The solid product filtered out will be saved and the rest (the ether and side products) tossed out. If the product is soluble in ether and the side-products are not, then the solid that is filtered would be tossed out and the ether and the desired product it contains will be kept. Purification of the product could be done by evaporating the volatile ether under a fume hood.
Why is nitric acid kept in air tight reagent bottle?
Because nitric acid is highly fuming liquid, it spreads in air and is highly corrosive.
Can't get your roboreptile to work?
Well i could not get my roboreptile to work ether but i kept pressing up and it started to work PS i doesn't need to be programmed
For years to come Scrooge always keeps?
He always kept Christmas
Where should dentures be kept?
Always in water
When returning from sea a green navigational buoys should be passed in what manner?
Always kept on portside
Why are liquids like ether and acetone kept in cool places?
well ether tend to evaporate easily in room temperature, lowering the temperature would probably lower the chance of it evaporating. Also, they're both flammable; keeping them below their flash point reduces the chance of an explosion.
