When sulfuric acid is added to marble chips, a chemical reaction takes place in which the acid reacts with the calcium carbonate in the marble to produce carbon dioxide gas. This gas forms bubbles which can create a layer around the marble chips, limiting further contact with the acid and slowing down the reaction. Once the layer of gas forms, the reaction rate decreases, resulting in the rapid reaction coming to a halt.

What happens when dilute sulphuric acid is added to copper oxide?
When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.
What is observed when copper oxide is added into excess dilute sulphuric acid?
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.
When silver coloured metal is added to dilute sulphuric acid solution?
When silver metal is added to dilute sulphuric acid solution, a redox reaction takes place. The silver metal reacts with the sulfuric acid to produce silver sulfate and hydrogen gas. The reaction can be represented by the following equation: 2Ag(s) + H2SO4(aq) -> Ag2SO4(aq) + H2(g)
Why is 4 normal sulphuric acid added to the titration flask?
4-nitroaniline, an organic compound, is being titrated with sulphuric acid in the mixture to help solubilize the compound. This aids in the reaction and allows for accurate titration results to be obtained.
What will happen if you put marble in hydrochloric acid?
Marble is made out of mostly carbonates. When any acid, including hydrochloric acid, is added to a carbonate, carbon dioxide will form. The acid may bubble as the reaction takes place, and some or all of the marble will be destroyed.
What is the reaction when sulphuric acid is added to calcium carbonate?
The reaction is:CaCO3 + H2SO4 = CaSO4 + CO2 + H2O
What is given off by table salt added with sulphuric acid?
Any reaction occur.
What did you observe when concentrated sulphuric acid was added to the reaction mixture?
I think it makes the equation to be more balanced
When zinc is added to sulphuric acid what gas produced?
The gaseous product in this reaction is 'hydrogen' and the salt is zinc sulfate.

What type of reaction takes place when sulphuric acid added to barium chloride?
acids and bases always react to give a salt and some water.
The reaction between sulfur trioxide and water is called?
Dissolution of SO3 in water. to form sulphuric Acid. Industrially, sulphur trioxide is dissolved in sulphuric acid to form oleum. Oleum ( fuming sulphuric acid) is seriously nasty stuff. SO3 + H2SO4 = H2S2O7 The oleum is then slowly dissolved in water to form sulphuric acid of the given molarity(strength). H2S2O7 + H2O = 2H2SO4 It is done this way in order to prevent 'spitting and fuming'. added to which you form twice a mush sulphuric acid.

Acid is added to a beaker containing crushed marble what effect does the stirring this mixture have on the system?
When acid is added to crushed marble, a chemical reaction occurs between the acid and calcium carbonate in the marble, producing carbon dioxide gas, water, and a salt. Stirring the mixture enhances the reaction by increasing the contact between the acid and the marble particles, allowing for more effective dissolution and gas release. This agitation accelerates the reaction rate, leading to a quicker production of bubbles and more vigorous effervescence. Overall, stirring facilitates a more uniform and rapid reaction within the system.
