Question

The equation for the ion product constant of water reveals that a solution's concentrations of hydronium ion (H,0') and hydroxide ion (OH ) are inversely proportional since they are on the same side of the equation. If a hydroxide ion is known, then the concentration of the other can be calculated using the ion product constant of water Part A I solution's concentration of HO increases, then its concentration of OH decreases. If a solution's of HO decreases, then its concentration of OH increases. This equation also reveals that if the concentration of either the hydronium ion or the on c ion concentrations (H,O' using the ion product constant of water (K) Hydronium ion concentration [H30' Greater than 1x107 M Equal to 1 x 10 M Solution condition It may help to keep the following equation in mind as you work KwalHso.IOH|-11x107Ml1 x 10 7M=1x10 14M Drag the appropriate items to their respective bins.

Explanation / Answer

Acidic                                    Neutral                                             Basic

[OH-] = 6*10^-12M       [OH-] = 1*10^-7M                             [OH-] = 4*10^-2M

[OH-] = 3*10^-9M                                                                  [OH-] = 7*10^-4M

[OH-] = 8*10^-10M                                                                [OH-] = 1*10^-5M

[OH-] = 7*10^-13M

part-B

                    [H3O+] = 2.2*10^-5M

                   [OH-]    = Kw/[H3O+]

                                = 1*10^-14/2.2*10^-5   = 4.5*10^-10M

part-C

                      [OH-]   = 1.5*10^-2 M

                      [H3O+]   = Kw/[OH-]   = 1*10^-14/1.5*10^-2 = 6.6*10^1-3M
