What happens when a few drops of concentrated sulphuric acid are made to fall on a piece of cloth?

Sulphuric acid is strong acid, which makes it react vigorously with substances. When a drop of sulphuric acid is put on the cloth, it causes degradation of cloth and creates hole in it.

What does sulfuric acid do to clothes?

Usually, this is accidental contact during use, transportation, or storage of a strong mineral acid, such as sulfuric or hydrochloric acid. These acids are capable of easily weakening cellulose (cotton) fibers, but synthetics (polyester) are much more resistant.

What is the Colour of a cotton shirt or jeans after having spilled conc H2SO4 on them?

It appears a yellowish coloration that becomes black due to the acid reactions with the cellulose of the fabric. Since cellulose has chemical formula of (C6H10O5) n, remains the maximum carbon yield (if hydrogen and oxygen are removed as water).

What happens when concentrated sulphuric acid is added to a piece of copper?

Copper reacts with hot and concentrated sulphuric acid to form copper sulphate, sulphur dioxide gas and water.

When conc h2so4 comes in contact with sugar it becomes black due to?

dehydration
${H_2}S{O_4}$ comes in contact with sugar, it becomes black due to dehydration. Because when sulphuric acid reacts with sugar then water is released as a product.

How is concentrated sulfuric acid made from oleum?

Combining of sulfur and oxygen (O2) to form sulfur dioxide, then purify the sulfur dioxide in a purification unit. The sulfur trioxide formed is added to sulfuric acid which gives rise to oleum (disulfuric acid) The oleum is then added to water to form sulfuric acid which is very concentrated.

What are the effects of sulfuric acid?

Sulfuric acid is a highly corrosive chemical that is potentially explosive in concentrated form. It can cause severe skin burns, can irritate the nose and throat and cause difficulties breathing if inhaled, can burn the eyes and possibly cause blindness, and can burn holes in the stomach if swallowed.

What does sulfuric acid do to cotton?

For example, if sulfuric acid of 70\% concentration is applied to a textile made of polyester and cotton, the cotton dissolves but the polyester does not. Therefore, measuring the remaining fibers clarifies the mix ratio of polyester and cotton.

Can h2so4 burn skin?

Sulfuric acid is a very strong chemical that is corrosive. Corrosive means it can cause severe burns and tissue damage when it comes into contact with the skin or mucous membranes.

What happens if you drink sulfuric acid?

Drinking concentrated sulfuric acid can burn your mouth and throat, and it can erode a hole in your stomach; it has also resulted in death. If you touch sulfuric acid, it will burn your skin.

How does it react with conc sulphuric acid?

The reaction between sulphur and conc. Sulphuric acid forms sulphur dioxide and water. By the change in the oxidation state, the oxidised and reduced species or oxidiser or reducer can be determined.

What happens when sulphur is heated with concentrated H2 S o4?

Sulphur is oxidised to sulphur dioxide by hot and concentrated sulphuric acid, and the acid also gets reduced to the same product (sulphur oxide) by sulphur.

What happens when sulphur reacts with sulphuric acid?

Sulphur is oxidised to sulphur dioxide by hot and concentrated sulphuric acid, and the acid also gets reduced to the same product (sulphur oxide) by sulphur. So H 2 SO 4

Why does a full bottle of sulfuric acid overflow?

Concentrated sulfuric acid is highly hygoscopic, absorbing air moisture quickly. Moisture is matter, and matter occupies space. Since the bottle is already full, as you state, the excess matter has no space inside the bottle, and the acid overflows.

What should I know about handling and injection of sulfuric acid?

Handling and Injection of the acid requires some special considerations. Concentrated sulfuric acid (93\%-98\%) is an oily liquid with a density nearly twice that of water and a viscosity similar to honey.

Is sulfur a reducer or reducer of sulphur?

A redox reaction takes place between thesulfur and sulfuric acid, forming sulphur dioxide and water. Sulphur is oxidised to sulphur dioxide by hot and concentrated sulphuric acid, and the acid also gets reduced to the same product (sulphur oxide) by sulphur. is reduced. So sulfur is a reducer.
