Instead of dilute sulphuric acid, dilute hydrochloric acid is taken

It seems like you're asking about a scenario in a chemical reaction where dilute hydrochloric acid is used instead of dilute sulphuric acid. However, without more context or a specific question, it's difficult to provide a detailed answer.

In general, both dilute sulphuric acid and dilute hydrochloric acid are strong acids that can donate protons (H+) to a solution. The choice between the two often depends on the specific requirements of the chemical reaction. For example, sulphuric acid is often used in reactions where a dehydrating agent is needed, while hydrochloric acid is often used when a chloride ion is needed.

If you could provide more details or specify the reaction you're referring to, I could give a more precise answer.
