2) Base is a molecule or ion able to accept a hydrogen ion from an acid.

3) A compound with particular chemical properties including neutralizing or effervescent with acids, typically a corrosive substance of this kind such as lime or soda.

4) Salt is a substance is a substance produced by the reaction of an acid with a base, salt consists of a positive ion of a base and negative ion of an acid. This term can also be use to refer to sodium chloride (table salt)]]> 2021-08-12 14:00:15 UTC https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676853603 selvaraj_sathya_jeevan https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676885939 When acids react with a metal , a salt and hydrogen gas produced 
Metal + acid ➡️ salt + hydrogen 
Aluminium foil  is placed with vinegar. Rapid bubbling but slow reaction at first. ]]> 2021-08-12 14:21:43 UTC https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676885939 selvaraj_sathya_jeevan https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676896740 When acids react with a carbonate , salt and carbon dioxide gas and water are produced.
The carbon dioxide causes bubbling during the reaction which is observed  as effervescence. It can be detected by passing gas through limewater which white forming on top.
Metal + carbonate ➡️salt + water+ carbon dioxide ]]> 2021-08-12 14:28:14 UTC https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676896740 selvaraj_sathya_jeevan https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676898498 Adding baking soda into vinegar]]> 2021-08-12 14:29:27 UTC https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1676898498 selvaraj_sathya_jeevan https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1679407704 2021-08-15 11:17:05 UTC https://padlet.com/selvaraj_sathya_jeevan/8djsdkqbrk2pyfql/wish/1679407704
