Question

write an activity to show the reaction of acids with metal?​

Answer 1

Answer:

when zinc reacts with hcl hydrogen gas is released

Answer 2

Explanation:

Set the apparatus as shown in figure.

Take about 10 ml of dilute HCl in a test tube and add a few zinc granules to it.

We will observe the formation of gas bubbles on the surface of zinc granules.

Pass the gas being evolved through the soap water.

Gas filled bubbles are formed in the soap solution which rise into the air.

Bring a burning candle near the gas filled bubbles.

The gas present in a soap bubble burns with a ‘pop’ sound.

Result:

Only ‘hydrogen’ gas burns making a ‘pop’ sound.

So we will notice that gas evolved is { H }_{ 2 }.
