What do u observe when hydrogen sulphide is passed through lead nitrate solution?

H2S is passed through lead nitrate solution to form nitric acid , seperate leadsulphide with evolution of H2 gas.

What happens when hydrogen sulphide gas is passed through the solution of lead chloride?

Solution. When hydrogen sulfide gas is passed through lead acetate solution, it forms a black precipitate of lead sulfide.

What is the Colour of the precipitate formed when H2S is made to react with lead nitrate?

it is a precipitation reaction in which PbS will be formed which is a black insoluble compound .

Why is hydrogen passed through lead nitrate?

The impure hydrogen is passed through lead nitrate [Pb{NO3}]2 solution to remove hydrogen sulphide gas present as impurity…..

What do you observe when a lead nitrate is heated?

When lead nitrate is heated in air, it decomposes to give lead oxide, a reddish brown coloured nitrogen dioxide gas and oxygen.

What do you observe when lead nitrate and silver nitrate is heated?

a) On heating Lead nitrate it decomposes to give a yellow residue of Lead oxide and brown Nitrogen dioxide with the evolution of Oxygen gas. b) Exposure of Silver chloride to sunlight leads to thermal decomposition of silver chloride which results in silver chloride break down into silver and chloride.

What do you observe when hydrogen sulphide gas is passed through copper sulphate solution?

When hydrogen sulphide is passed through a blue solution of copper sulphate, a black precipitate of copper sulphide is obtained, and sulphuric acid so formed remains in the solution.

What do you observe when H2S gas is passed through copper sulphate solution?

When hydrogen sulphide gas is passed through a blue solution of copper sulphate, a black precipitate of copper sulphide is obtained and the sulphuric acid so formed remains in the solution.

What do you observe when HCL is passed through silver nitrate solution?

white precipitate
When Hydrogen chloride gas is passed through a solution of silver nitrate then white precipitate of silver chloride -\[\;AgCl\] can be observed at the bottom of the test tube or vessel. As we can see in the above chemical equation, two products are formed, precipitate of silver nitrate and nitric acid.

What do you observed when Hydrogen chloride gas is passed through lead nitrate solution and the product thus formed is heated?

HCl is added to lead nitrate solution and heated, it forms a white precipitate of lead chloride. 2.
