Question

please write an experiment of double displacement reaction in the form of aim,apparatus,procedure,observation ,conclusion,precautions

Answer 1

Hope you understood................

Answer 2

Answer:

➡Aim:-

To show the interaction between zinc granules and hydrochloric acid or sulphuric acidformation of H gas)

➡Apparatus:-

Zinc granules, conical flask, test tube, hydrochloric acid / sulphuric acid

➡Procedure:-

Take a few zinc granules in a conical flask or a test tube. Add dilute hydrochloric acid or sulphuric acid to this.

Touch the conical flask or test tube.

➡Observation: -

A gas is evolved and the conical flask is warm

➡Conclusion:-

From this we conclude that when a chemical reaction takes place there is a change in the state, colour, and temperature.

Zn + 2HCl → ZnCl2 + H2↑ + heat .

Zn + H2SO4 → ZnSO4 + H2↑ + heat.

this is your answer.....
