accuracy - how close a measurement is to a true or accepted value acid - proton donor Acid Naming Rules - 1. Add O, add "per" prefix. 2. Subtract 1 O, ending in "ous". 3. Subtract 2 O's, add "hypo" prefix with "ous" suffix. acid-base titration - a solution of a known concentration (standard) is added gradually to another in order to determine the concentration actual yield - the amount of actual product formed in a reaction Ag⁺ - Silver cation Al³⁺ - Aluminum cation allot...
