Why concentrated Sulphuric acid is always added to water and not the water to concentrated Sulphuric acid why the mixture gets hot?

If water is added to a concentrated acid, It is highly exothermic process, the heat generated may cause the mixture to splash out and cause burns. When the acid is added to water slowly with constant stirring, the mixture will not splash out.

Why is concentrated H2SO4 diluted by adding acid into water but not water into acid?

So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container and all this because the reaction is exothermic. On the other hand, adding acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize it.

Why do we add acid to water and not water to acid?

When you mix acid with water, it’s extremely important to add the acid to the water rather than the other way around. This is because acid and water react in a vigorous exothermic reaction, releasing heat, sometimes boiling the liquid. When you add water to acid, the water boils and the acid may splatter and splash!

Why is sulfuric acid diluted by adding the acid to the water rather than adding water to the acid?

Sulfuric acid (H2SO4) is the most dangerous common acid to dilute. The acid is much heavier than water, so water added to it reacts with the top layer first. A lot of heat gets generated, even when sulfuric acid and water are mixed properly.

What happens if water is added to concentrated sulphuric acid?

Reaction with water If water is added to concentrated sulfuric acid, it can boil and spit dangerously.

What would happen if H2SO4 is not added to water?

If H2SO4 is not added to water during electrolysis, the conductivity of the water will be low which results in slow electrolysis. When H2SO4 is added, the conductivity increases resulting in quick electrolysis.

What would happen if dilute H2SO4 is not added to water?

Acid dissociates to produce ions which result in increased conductivity. So, if H2SO4 is not added to water, the conductivity of water will remain low resulting in slow electrolysis.

Why is it important to dilute concentrated sulphuric acid?

Concentrated sulphuric acid (H2SO4) is a hazardous, highly corrosive chemical, which must be handled with great care. The dilution of sulphuric acid is a highly exothermic (heat generating) reaction.

Why is h2so4 added to water during electrolysis?

Ans :Electrolysis of pure water is very low because water is an covalent compound so it can’t ionize to release ions. To increase the conductivity of water a few drops of sulphuric acid is added .

When concentrated acid is added to water whether the process is exothermic or endothermic?

When concentrated acid is added to water it is an exothermic process as heat is released.

What will happen if H2SO4 is not added to water?

Why is it important to dilute concentrated Sulphuric acid?

What happens when you mix H2SO4 and H2O?

H2SO4 + H2O → H3O + HSO4. When you mix concentrated sulfuric acid water, you pour the acid into a larger volume of water. Sulfuric acid (H2SO4) react very vigorously with water to highly exothermic reaction. If you add water to concentrated sulfuric acid,it can boil and spit and you may get a nasty acid burn.

Does adding acid to water make it more concentrated?

When you mix strong acids and water, it makes a difference whether you add acid to water or water to acid. Always add acid to water and not the other way around. If you add a little water to a lot of concentrated acid, the resulting solution is still concentrated.

What is the reaction between H2O and sulphuric acid?

The reaction of water (H2O) and sulphuric acid (H2SO4) is very exothermic and gives out heat.(however, this answer is in accordance with school textbooks. in real cases the reaction of even 98\% pure H2SO4 with water isn’t to much exothermic) If water is added to the concentrated sulphuric acid,…

What happens when you mix concentrated sulfuric acid and water?

Since concentrated sulfuric acid of about 8M is denser than water, the water will float on the surface and the reaction begins there. When you mix concentrated sulfuric acid water, you pour the acid into a larger volume of water. Sulfuric acid (H2SO4) react very vigorously with water to highly exothermic reaction.
