Q: Answer the following question given this paragraph: Acids have some properties in common. They turn litmus, a plant extract, red. They react with some metals to give off H2 gas. They react with carbonate and hydrogen carbonate salts to give off CO2 gas. Acids that are ingested typically have a sour, sharp taste. (The name acid comes from the Latin word acidus, meaning "sour. ") Bases also have some properties in common. They are slippery to the touch, turn litmus blue, and have a bitter flavor if ingested. Acids and bases have another property: they react with each other to make water and an ionic compound called a salt. A salt, in chemistry, is any ionic compound made by combining an acid with a base. A reaction between an acid and a base is called a neutralization reaction and can be represented as follows: acid + base H2O + salt The stoichiometry of the balanced chemical equation depends on the number of H+ions in the acid and the number of OH ions in the base. Q: What type of ionic compound is formed from acid and bases reacting with each other? A:
A:
