Chemical Properties Of Acids
Acidic, Basic and Neutral materials of Class 7
REACTION OF ACIDS WITH METALS:
When acid reacts with a metal, then salt and hydrogen gas are formed.
For example
Metal + Acid → Salt + Hydrogen gas
- The reaction of dil with zinc metal.
Experiment:
zinc granules are taken in glass with 5 ml dilute sulphuric acid, due to the reaction of an acid with metal hydrogen gas forms and produces bubbles
- Gas test: Bring a burning candle near the gas-filled soap bubble.
- Observation: The gas present in the soap bubble burns with a pop sound which shows the gas that evolved during the reaction is hydrogen gas.
