What happens when dilute sulphuric acid is poured on a copper plate with equation?
Answer: Copper does not react with dilute sulphuric acid. So, no reaction takes place when dilute sulphuric acid is poured on a copper plate. This happens because iron; being more reactive than copper; displaces copper from copper sulphate and makes iron sulphate.
What is formed when dilute sulphuric acid is poured on a copper plate?
hydrogen gas
When dilute sulphuric acid poured on a copper plate, the metal does not react with sulphuric acid. But when concentrated sulphuric acid is poured over the copper plate, it librates hydrogen gas.
What happen when copper react with sulphuric acid?
Copper reacts with hot and concentrated sulphuric acid to form copper sulphate, sulphur dioxide gas and water.
What happens when dilute sulphuric acid is poured on silver plate?
a) Silver sulphate is formed.
Why the copper do not react with dilute H2SO4?
Copper does not react with dilute sulphuric acid. This is because copper is lower in reactivity series than hydrogen. Copper has higher reduction potential than that of hydrogen. Thus, copper cannot displace hydrogen from the non-oxidising acid.
What happens when dilute sulphuric acid is poured on iron filings?
When dilute sulphuric acid is added to the mixture of iron filings and sulphur, the iron part reacts with sulphuric acid and hydrogen gas is produced which is a colourless and odourless gas.
Which does not react with dilute sulphuric acid is?
Explanation: Copper is the only metal which does not react with dilute sulphuric acid.
What happens when dilute sulphuric acid is poured on a zinc plate?
When dilute sulphuric acid is poured on zinc granules, then zinc being more reactive than hydrogen displaces it from the acid and forms zinc sulphate and hydrogen gas. Hydrogen is a combustible gas and burns with a popping sound. This can be observed when a match stick which is burnt is bought ear to the test tube.
What happens when you put sulphuric acid on copper?
When dilute sulphuric acid poured on a copper plate, the metal does not react with sulphuric acid. But when concentrated sulphuric acid is poured over the copper plate, it librates hydrogen gas. This video explains the reaction of metals with cold water and acids.
What happens when copper nails are placed in dilute sulphuric acid?
(a) dilute sulphuric acid is poured on a copper plate? (b) iron nails are placed in copper sulphate solution? Write word equations of the reactions involved. a) C u do not react with dilute sulphuric acid as it comes behind hydrogen in the reactivity series.
What happens when C U reacts with dilute sulphuric acid?
Write word equations of the reactions involved. a) C u do not react with dilute sulphuric acid as it comes behind hydrogen in the reactivity series. But with concentrated H 2 is evolved. b) Since F e is more reactive than C u. It will displace C u from C uS O4 . A color change of blue to light green will occur.
Which is more reactive iron or copper sulphate?
Write word equations of the reactions involved. Since less reactive metals do not react with acids. Copper will not react with dilute sulphuric acid. Here, displacement reaction will take place. Iron (Fe) being more reactive than copper displaces copper from copper sulphate solution
