What do acids and bases do according to the Bronsted-Lowry definition? | Acids: Donate h+ Bases: accept H+ |
What do acids and bases do according to the Lewis Definition | Acids accept electron pairs and bases donates electron pairs |
The idea of conjugate acids and bases is based on the........ definition of acids and bases | Bronsted-Lowry |
The conjugate base/acid is the particle left over after an acid.. donates/accepts a proton | conjugate base donates |
The conjugate base/acid is the particle left over after an acid.. donates/accepts a proton | acid accepts |
What is a monoprotic acid? | donates one hydrogen |
What is a polyprotic acid? | can donate more than one |

Define amphoeteric and list the most common amphoteric substances | can either donate or accept hydrogen ions ex: water |
Which is stronger acid, HI with 60% ionization or h2S with 35% ionization | more ionization the more it dissociates so it is a strong acid |
the process of using a specific volume of a solution with known concentration to react with a measures amount of solution of unknown concentration is called | titration |
