What is the hydroxide ion concentration, [OH-], in a solution with a hydronium ion concentration, [H3O+]...
What is the hydroxide ion concentration, [OH-], in a solution with a hydronium ion concentration, [H3O+] = (1.42x10^-3) M? NOTE: The problem statement uses the caret symbol, "^" to indicate exponentiation and shows the entire value in parentheses. For example: The value 1.37 x 10-4 would be shown as (1.37x10^-4). Note: Your answer is assumed to be reduced to the highest power possible.
