Acid Base Strength Table

Acid Dissociation Constant K a

Amphoteric substance A substance that can act as either an acid or a base H 2 O + HCl  H 3 O+ + Cl- H 2 O + NH 3  NH OH-

Self ionization H 2 O + H 2 O  H 3 O+ + OH-

pH = - log [H+] ion concentration in moles per liter M

pH = negative log of the [H+] pOH = negative log of the [OH+] pCl = negative log of the [CL-] pCO = negative log of the [CO] PBanana = negative log of the [banana]

Ways to determine pH Taste Litmus Paper PH strips Indicators pH meter Acids react with metals or carbonates
