Question

In an aqueous solution that is basic, [h3o ] is ________ than 1.0 x 10-7 and ________ than [oh-].

Answer 1

In a basic solution, [H3O+] is less than 1.0 x 10^-7 M and also less than [OH-], indicating a higher pH value and a lower pOH value.

Step-by-step explanation:

In an aqueous solution that is basic, the concentration of hydronium ions ([H3O+]) is less than 1.0 x 10-7 M and also less than the concentration of hydroxide ions ([OH-]). This lower hydronium ion concentration corresponds to a pH value that is greater than 7.00. Conversely, the higher hydroxide ion concentration indicates a pOH value that is less than 7.00. As the [H3O+] decreases, the basicity increases, reflecting in a higher pH and lower pOH. For example, if you have a solution where the [H3O+] is 1 x 10-9 M, this solution is basic because it is less than 1 x 10-7 M.
