Question
If base is added to pure water, why does the [H3O+] decrease?
Put the terms in the appropriate blanks in the sentence.
a. reactants
b. decreased
c. [H3O+][OH-]
d. increased
e. [OH-]/[H2O+]
f. increases
g. [H2O+]/[OH-]
h. products
i. 1 x 10-7
j. 1 x 10-14
k. 1 x 10-10
l. decreases
The equilibrium for water shifts in the direction of the _______ as OH- is added, which __________ the [H3o+]. The [OH-] is _______ and the [H3O+] is __________ to maintain the product __________ equal to the kw value of __________.
Explanation / Answer
The equilibrium for water shifts in the direction of the reactants side as OH- is added, which decreases the [H3O+]. The [OH-] is 1 * 10^-7 and the [H3O+] is 1 * 10^-7 to maintain the product [H3O+][-OH] equal to the kw value of 1 * 10 ^-14.
