Answer: Lemon juice and vinegar are the acids that are found in everyday materials.
Step-by-step explanation:
Acids are the species that dissociate to give hydrogen ions and acids are sour in taste.
Whereas bases are the species that dissociate to give hydroxide ions. Bases are soapy in texture and bitter in taste.
For example, lemon juice contains citric acid and vinegar contains acetic acid.
On the other hand, baking soda is sodium bicarbonate which is a base and dish detergent and hand soap are also bases.
Therefore, we can conclude that out of the given options, acids that are found in everyday materials are lemon juice and vinegar.
