Ammonia is a weak base. Potassium hydroxide is a strong base. Which statement is correct?
A solution of potassium hydroxide will always have greater conductivity than a solution of ammonia.
A solution of potassium hydroxide will always have a lesser concentration of solute than a solution of ammonia.
A solution of potassium hydroxide will always have a higher pH than a solution of ammonia
A solution of potassium hydroxide will always have more OH– ions than a solution of ammonia.
A solution of potassium hydroxide will always have a higher pH than a solution of ammonia.
The correct statement is: A solution of potassium hydroxide will always have a higher pH than a solution of ammonia.
Ammonia, being a weak base, does not fully dissociate in water and therefore does not release as many OH– (hydroxide) ions as potassium hydroxide, which is a strong base. As a result, a solution of potassium hydroxide will have a higher concentration of OH– ions and a higher pH compared to a solution of ammonia.
