Question

If a solution is considered to be basic, which of the following is true about the hydroxide ion concentration?

A:the concentration of the hydroxide is less than the concentration of the hydronium ion

B:the concentration of the hydroxide ion is equal to the concentration of the hydronium ion

C:the concentration of the hydroxide ion is greater than the concentration of the hydronium ion

D:the concentration of the hydroxide ion does not matter when determining whether a solution is acidic or basic

Answer 1

it is C: the concentration of the hydroxide ion is greater than the concentration of the hydronium ion

Answer 2

The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion

Reason -

An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
