Sulphuric acid is kept in a stoppered bottle to prevent the release of harmful fumes and to minimize contact with air, moisture, and other substances that could react with the acid. This helps maintain the purity and concentration of the acid and ensures safe handling and storage.

What is the reaction of sulphuric acid in water?
When sulfuric acid is mixed with water, it undergoes a highly exothermic reaction, releasing heat. The reaction is highly exothermic, producing significant heat and potentially causing splattering. It is important to add the acid to water slowly while stirring to control the heat release and prevent splashing.
Why are the wooden shelves on which sulfuric acid is kept stained black?
The black stains on wooden shelves where sulfuric acid is kept are likely due to the acid reacting with the wood, causing carbonization and discoloration. This reaction can occur as sulfuric acid is a strong oxidizing agent that can break down organic materials like wood over time. It is important to store sulfuric acid in appropriate containers to prevent damage to shelves and ensure safety.
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 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.

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.
Why do soda bottle break when kept in refrigator for a long time?
because it is very cold.
