What tests could be safely used to distinguish a strong base from a weak base?

One way to distinguish a strong base from a weak base is by observing their properties such as the level of dissociation in water. Strong bases completely dissociate in water to form ions, resulting in a higher conductivity compared to weak bases. Another way is to measure the pH of the solution - strong bases will have a significantly higher pH (above 10) compared to weak bases which will have a pH closer to 7.
