Directions and/or Common Information:
pH = -log [H3O+]
The pH level of a substance is equal to the negative log of the concentration of the hydronium ion, [H 3O +]. [H3O+] × [OH-]= 1.0 × 10-14 In any substance, the product of the concentration of the hydronium ion, [H 3O +], and the concentration of the hydroxide ion, [OH -], is always equal to 1.0 × 10 -14 |
