They have a bitter taste They have a slimy, or soapy feel on fingers Most bases react with acids and precipitate salts. Strong bases may react violently with acids.Bases turn red litmus paper blue2. Answer;

An acid

Explanation;When acids are dissolved in water, the concentration of the acid decreases and it becomes dilute.
