【How-to】What happens when dilute h2 s o4

What happens when dilute H2SO4?

Materials: Metals and Non-Metals | Exercise

Solution: (a) Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. But when concentrated sulphuric acid is poured onto a copper plate, effervescence is observed.

How do you dilute H2SO4?

Fill a container about half way or more with distilled water, add the acid, and then bring up to volume with more water. In the example above, fill a flask with about 150 mL or more with distilled water, add 6.9 mL of concentrated sulfuric acid, then continue to dilute with water to the 250 mL mark.)

What happens when dilute H2SO4 is added to iron fillings?

a. When dilute sulphuric acid is added to a mixture of iron fillings and sulphur powder, reaction occusrs between dilute sulphuric acid and iron filings that forms ferrous sulphate and evolution of hydrogen. … FeS formed reacts with sulphuric acid to form ferrous sulphate and release hydrogendisulphide gas.

What happens when dilute H2 S o4 is added to zinc granules?

When we pour dilute sulphuric acid on zinc granules, zinc sulphate is formed and the hydrogen gas is evolved with an effervescence.

What happens when dilute sulphuric acid is poured on a copper plate a copper sulphate formed B zinc sulphate formed C copper chloride formed D zinc sulphate formed?

Answer: Copper does not react with dilute sulphuric acid. So, no reaction takes place when dilute sulphuric acid is poured on a copper plate. But when concentrated sulphuric acid is poured over copper plate, effervescence is observed. This happens because of formation of hydrogen gas.

What is observed when dilute h2 S o4 is added to a mixture of iron filings and Sulphur powder?

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.

Does sulphur react with dilute sulphuric acid?

The reaction between sulphur and conc. Sulphuric acid forms sulphur dioxide and water. By the change in the oxidation state, the oxidised and reduced species or oxidiser or reducer can be determined.

Which gas is produced when iron reacts with dilute h2so4?

it forms iron sulphate and liberate hydrogen gas. Fe + H₂SO → FeSO₄ + H₂.

What happens when dilute sulphuric acid is poured on silver plate?

The correct answer is Option (C) no reaction takes place. Silver does not react with dilute sulphuric acid. Explanation: Silver reacts with hot concentrated sulphuric acid and the reaction gives sulphur dioxide and water.

What happens when dilute hydrochloric acid is added to iron fillings tick the correct answer?

Answers (1)

When dilute hydrochloric acid is added to iron fillings then hydrogen gas and iron chloride are produced. Thus, option (a) is correct.

When dilute sulfuric acid is added to the mixture of iron fillings and sulfur iron fillings react with sulfuric acid and a colorless gas is produced the gas is?

Answer Expert Verified

The gas produced is hydrogen sulphide (H2S).

What happens when dilute sulphuric acid is poured on a copper plate for Class 8?

Answer: (a) When dilute sulphuric acid is poured on a copper plate, no reaction takes place due to less reactivity of copper. … Copper gets deposited on the iron nail and green solution is ferrous sulphate solution.

What happens when dilute sulphuric acid is poured on a copper plate Byjus?

The reaction shows that iron is more reactive than copper because it displaces copper from the copper sulphate solution. The iron passes into the solution as Fe (II) forming the ferrous sulphate solution.

What happens when iron sulphide reacts with dilute sulphuric acid?

When iron sulphide is added to dilute sulphuric acid, you will get iron sulphate, water and sulphur dioxide as the products.

What happens when dilute hydrochloric acid is added to iron fillings and Sulphur powder?

As part ‘A’ is heated, a compound FeS is formed by the reaction between iron filings and sulphur. When dilute HCI is added to part A, FeS will react with dil HCI to form H2S gas which has smell of rotten eggs and will turn lead acetate paper black.

What happens when iron sulphide reacts with sulphuric acid?

When dilute sulphuric acid reacts with iron sulphide the gas evolved is Hydrogen sulphide.

When dilute sulphuric acid is added to pieces of iron sulphide hydrogen sulphide gas is produced?

When dilute sulphuric acid is added to pieces of iron sulphide, the sulphate ion switches place with sulphide ion to form ferrous sulphate and hydrogen sulfide gas. Therefore, it is the right answer.

What happens when acid reacts with sulphide?

Sodium sulphite reacts with sulphuric acid to produce sodium bisulfate, sulfur dioxide and water.

When iron sulphide FeS is treated with dilute sulphuric acid then a gas is produced with smell of rotten eggs identify the gas?

A rotten egg smell gas which is acidic in nature is Hydrogen sulphide gas.

Which gas is liberated when ferrous sulphide is treated with dilute sulphuric acid?

Hydrogen disulphate gas liberated when dilute sulphuric acid reacts with iron sulphide.

Which liberates hydrogen sulfide on reaction with ferrous sulphide?

Reactions. Iron sulfide reacts with hydrochloric acid, releasing hydrogen sulfide: FeS + 2 HCl → FeCl₂ + H₂S.
