Close to that of pure water
Unaltered
Greater than 8.4
Less than 8.4
Correct answer is C
A strong base is one that fully dissociates to give ions in solution. Weak bases only partially dissociate in a solution,
while the strong bases dissociate fully in a solution. Weak bases have pH 7.3 – 10, strong ones have pH 10 – 14.
