What happens when ethanol is heated in presence of concentrated H2SO4?
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
What gas evolved when potassium nitrate crystals are heated with concentrated sulphuric acid?
When potassium nitrate crystals are heated with concentrated sulphuric acid, nitric oxide gas (NO) is evolved. This is a result of the oxidation of nitrate ions in potassium nitrate by the sulphuric acid.
When concentrated nitric acid is heated with sulfur whih acid is obtained?
Sulphuric acid
What are the Ways to convert dilute sulphuric acid to concentrated sulphuric acid?
One way to convert dilute sulphuric acid to concentrated sulphuric acid is through a process called evaporation. In this method, the dilute acid is heated to evaporate the water content, leaving behind the concentrated acid. Another method involves adding concentrated sulphuric acid to the dilute solution until the desired concentration is achieved.
What happens when concentrated sulphuric acid is heated with oxalic acid?
When concentrated sulfuric acid is heated with oxalic acid, oxidation of oxalic acid takes place, giving off carbon dioxide gas and water as byproducts. This reaction can be used to generate carbon dioxide for various applications.
What is the reaction of hexane in sulphuric acid?
Hexane does not react with concentrated sulphuric acid under normal conditions. However, if heated strongly, it may undergo dehydration to form alkenes.
What happens when oxalic acid is heated with concentrated sulphuric acid?
product is formed
What happens when copper is added to concentrated sulfuric acid and heated gently?
copper sulphate and hydrogen is released.
How can you heat water without using fire?
Heat can be generated in many ways- friction, chemical action, electrical resistance, solar energy, etc. Fire is quick and easy, but if you have an electric stove or microwave, you use a non-fire heating process all the time.
What happens when litharge is heated with concentrated h2so4?
When litharge (lead(II) oxide) is heated with concentrated sulfuric acid (H2SO4), lead sulfate (PbSO4) is formed along with water. The reaction is as follows: PbO(s) + H2SO4(l) → PbSO4(s) + H2O(l)
Sodium formate is heated with conc sulphuric acid?
When sodium formate is heated with concentrated sulfuric acid, it undergoes dehydration to form sodium oxalate and water. This reaction typically occurs at elevated temperatures and can be used as a method for preparing sodium oxalate.
How do you separate ethanol from aqueous ethanol?
Ethanol can be separated from aqueous ethanol through a process called distillation. In distillation, the mixture is heated to evaporate the ethanol, which is then condensed back into liquid form. The condensed ethanol can then be collected as a separate product.
