You are given a piece of charcoal. How will you find out whether it forms basic oxide or acidic oxide.

Explanation

The piece of a charcoal may be taken on a deflagrating spoon and burnt, lowering the spoon in a gas jar. After the charcoal piece has burnt, some water may be added in the gas jar. Now the solu- tion may be tested with blue litmus if it turns red then the solution is acidic.
`underset("Carbon")(C)+ underset("Oxygen")(O_2) overset("heat")(rarr) underset("Carbon dioxide")(CO_2)`
`underset("Acidic oxide")(CO_2)+underset("water")(H_2O) overset("heat")(to) underset("Carbonic acid")(H_2CO_3)`
