Question

List an acid's taste, touch, indicator, reaction, and conductivity.

a) Sour; Corrosive; Litmus turns red; Reacts with metals; Conducts electricity.
b) Bitter; Slippery; Phenolphthalein turns pink; Reacts with bases; Non-conductive.
c) Sweet; Oily; Blue litmus unchanged; Reacts with salts; Variable conductivity.
d) Salty; Grainy; Universal indicator varies; Reacts with gases; Insufficient data on conductivity.

Answer 1

Acids have a sour taste and can turn blue litmus paper red. They react with metals and carbonate salts. Acids can also conduct electricity.

Step-by-step explanation:

Acids have a sour taste and can be found in foods such as lemons and vinegar. They turn blue litmus paper red and react with metals to produce hydrogen gas. Acids also react with carbonate salts to release carbon dioxide gas. Additionally, acids can conduct electricity.
