Why sulphuric acid is used in laboratory preparation of carbon dioxide?
Carbon and its compounds | Exercise Solution: Concentrated sulphuric acid removes molecules of water from formic acid. It acts as a dehydrating agent in formation of carbon monoxide.
Why concentrated sulphuric acid is not used in preparation of hydrogen?
Conc. sulphuric acid is not used in the preparation of hydrogen as it will produce sulphur dioxide.
What reacts with sulphuric acid and carbon dioxide?
The chemical reaction is known as the neutralization reaction. Thus, sulphuric acid reacts with sodium carbonate to give sodium sulphate with molecular formula of Na2SO4 . The other products are carbon dioxide and water.
Why is dilute Tetraoxosulphate VI acid not suitable for preparing carbon dioxide?
Answer: Because this does not dissolve in water – it forms a barrier on the surface of the unreacted CaCO3 which prevents any further reaction. A small volume of CO2 is produced , but this stops after a short time .
Which acid Cannot be used to prepare CO2 gas in lab?
Why is sulphuric acid not used for the preparation of carbon dioxide in the laboratory?
Why is sulphuric acid not used during the reaction of alcohols with Ki?
In the presence of a dilute acid, KI would produce HI. If the acid used is sulphuric acid, the HI gets used up to produce I2 gas. As a result, the action of alcohol on acid to produce alkyl iodide cannot occur. Therefore, sulphuric acid is not used for this reaction.
Can we use concentrated sulphuric acid in place of dilute sulphuric acid in the laboratory preparation of hydrogen gas give reason for your answer?
Dilute sulphuric acid cannot be replaced by concentrated acid in the preparation of hydrogen because it is a strong oxidising agent and it will produce sulphur dioxide.
Does carbon react with dilute sulphuric acid?
Dilute Sulphuric Acid has no reaction with carbon, while Conc. Sulphuric Acid reacts with carbon over a temperature range of 25–150 degree C (roughly) forming Carbon Di Oxide gas, Sulphur Di Oxide gas and Water.
What happens when carbon react with sulphuric acid?
Carbon reacts with sulfuric acid to produce carbon dioxide and sulfur dioxide gas along with water. Sulfuric acid should be a concentrated, heated solution.
Which of the following does not produce CO2 when treated with concentrated H2SO4?
Which of the following substances will not give carbon dioxide on treatment with dilute acid? Lime, CaO (calcium oxide) does not evolve CO2 when reached with dilute acid.
Why is CO2 not collected by the downward displacement of water?
Answer: carbon di oxide gas is soluble in water…. therfore it cannot be collected by downward displacement of water since it will dissolve in water if collected.
What do you observe when dilute h2so4 acid is used instead of Dil HCL during the preparation of CO2 gas?
If sulphuric acid is substituted for hydrochloric acidic the reaction produces calcium sulphate which creates an impervious coating on the marble that slows down the reaction. The evolution of CO2 slows down. So it’s not very useful to use marble chips and sulphuric acid to produce CO2.
