What is the reaction of sulphuric acid in water?
It is an exo thermal reaction. It means, heat is produced when they get mixed together.So, we have to be very, very careful while adding water with sulphuric acid, in case to get it diluted, because enormous heat will be produced.You should not pour water on sulphuric acid kept in a bowl. It is very dangerous. Why?Just think. When you pour water on sulphuric acid, enormous heat will be produced which make water to expand abruptly and so an explosion becomes possible which in turn spills the acid all around and even on the person who has poured water on it.So the intelligent way is, instead adding water to the acid it will be better adding acid to water. That too, using a glass rod. Sulphuric acid is poured in smaller amount at top edge of the glass rod kept inclined in a bowl containing water. The acid slowly descends into the water and as soon as it descends heat will be produced. So using another glass rod we have to stir well the water in the bowl so that the heat produced will be distributed all over.This is the right technique to prepare dilute sulphuric acid.The balanced equation is:H2SO4 + 2H2O -> 2H3O+ + SO42-
Why are the wooden shelves on which sulfuric acid is kept stained black?
Sulphuric acid has an extreme attraction for water, and it can pull the hydrogen and oxygen (the component atoms of water) out of a material such as cellulose, which is primarily what wood is made of, and this leaves behind carbon, which is, of course, black. It is equivalent to charring in a fire.
Why is nitric acid kept in air tight reagent bottle?
Nitric acid is highly corrosive and can react with moisture in the air, forming nitrogen dioxide gas. Storing it in an airtight container helps prevent these reactions and ensures the acid remains at its desired concentration and potency.
How do you store sulphuric acid?
Sulfuric acid should be stored in a cool, well-ventilated area away from sources of heat or ignition. It should be kept in a tightly sealed container made of a chemically resistant material like polyethylene or glass. Additionally, it should be stored separately from incompatible materials to prevent reactions or spills.
Why a tightly capped bottle full of water is kept in the open sunlight tiny bubbles are formed all around the bottle?
When a tightly capped bottle of water is kept in the open sunlight, it heats up and the water inside starts to evaporate. The evaporation process releases gases trapped in the water, creating bubbles around the bottle. The heat from the sunlight accelerates this process.

Why does water move upward when kept in a bottle with a cork and made a hole and kept a straw and poured hot boiling water on the bottle?
gangam style solves everyones problems!

Why do we get dew on the surface of a cold soft drink bottle kept in air?
Moisture in the air condenses on the cold bottle. If the air is dry, there will be no dew on 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 we get dew on the surface of a cold soft drink bottle kept in open air?
Moisture in the air condenses on the cold bottle. If the air is dry, there will be no dew on the bottle.

Is olive oil a acid or alkali?
They are alkaline if kept in oil.

Why ariated water bottle kept under water during summer?
Because the air expands during summer, which leads to the breaking of bottle; so to avoid this, it is kept under water.
How long does a bottle of jack Daniels keep unopened?
As long as it is kept cold, indefinitely.
