Answer :

Acid:

Acid, any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).

Community :

A community is a group of living things sharing the same environment. They usually have shared interests. In human communities, people have some of the same beliefs and needs, and this affects the identity of the group and the people in it.
