False

Explanation;

Bases have some of the following properties;

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. It dissociates in water to give H+ ions or hydrogen ions.All acidic solutions contain more hydrogen ions than hydroxide ions, therefore when added to water it increases the concentration of H+ ions in water, as water is a neutral substance whose concentration of H+ ions is equal to OH-.
