Acids are classified as Organic Acids and Mineral Acids. Acids which are derived from plants and animals, they are known as Organic Acids. For Example, Citric Acid from fruit. Mineral acids are inorganic acids such as Sulphuric Acid. They are dangerous to be used, so need more precautions.
Acids are also classified as Strong Acids or Weak Acids. Strong acid is an acid, that completely dissociates into ions in aqueous solutions. For Example, Sulphuric Acid, Hydrochloric Acid.
Weak acid is the one which does not dissociate completely into ions in aqueous solutions. For Example, Acetic Acid.

Aim : To show the reaction of acids with metals.
Required Materials : 1. Test tube 2. Delivery tube 3. Glass trough 4. candle 5. Soap water 6. Dil. HCl 7. Zinc granules.
Procedure :
- 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 }.
Additional Experiment: - Repeat the above experiment with H_{2}SO_{4} and HN{{O}_{3}}.
- We observe the same observation of the HCl experiment.
Conclusion : From the above activities we can conclude that when acid reacts with metal, H2 gas is evolved.

The role of sunlight in photochemical decomposition reaction is as follows -
• The photochemical decomposition reactions are chemical decomposition reactions which are caused by the application of the light rays or photon particles.
• Now, from the above mentioned definition,we came to know that the application of the light rays or photon particles,is mandatory to perform of photochemical decomposition reaction.
• And, sunlight is a good source of light rays and photon particles. That's why, sunlight is very important for different photochemical decomposition reactions.
