Which one of the following solution on mixing will not form a precipit...
Explanation:
Iron sulphide and dilute sulphuric acid:
- When iron sulphide reacts with dilute sulphuric acid, it forms hydrogen sulfide gas and iron(II) sulfate.
- Since hydrogen sulfide gas is a gas and not a solid, no precipitate is formed in this reaction.
- Therefore, this combination will not form a precipitate.
Lead acetate and potassium iodide:
- When lead acetate reacts with potassium iodide, it forms lead iodide which is insoluble in water and hence, a yellow precipitate of lead iodide is formed.
Lead nitrate and sulphuric acid:
- When lead nitrate reacts with sulphuric acid, it forms lead sulfate which is insoluble in water and hence, a white precipitate of lead sulfate is formed.
Potassium bromide and silver nitrate:
- When potassium bromide reacts with silver nitrate, it forms silver bromide which is insoluble in water and hence, a cream precipitate of silver bromide is formed.
Therefore, out of the given options, only the combination of iron sulphide and dilute sulphuric acid will not form a precipitate.
