If a solution is basic, which of the following is true?

a. ph = poh
b. [h3o+] > [oh-]
c. [h3o+] = [oh-]
d. [h3o+] < [oh-]
e. none of the above

D. [H3O+] < [OH-]

Explanation:

A basic solution has pH > 7 so

pH = pOH - FALSE

This is neutral one.

Where [H3O+] = [OH-]

[H3O+] > [OH-] This occurs in the acidic solution, where the [H3O+], so the pH is so low.

[H3O+] < [OH-]

This is the basic solution, a pH >7, where the [OH-] is higher than  [H3O+]

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
