The conjugate base of a weak acid is always a strong base
True
pH below 7 always is acid, base has pH above 7.

The pH of a weak base can be anything greater than 7.0. Generally, weak bases do have a lower pH that strong bases, but this is not always true. The fact that a base is weak only means that it does not completely ionize in solution. The pH of a weak base depends only upon the concentration of hydroxide ions (OH-) in solution.
The conjugate base of a weak acid is always a strong base
True
pH below 7 always is acid, base has pH above 7.
It is a weak base
Borax is a weak base.
Ammonia is a weak base
No, NH3 is a weak base, as it tends to capture free protons.
weak
The base angles are always congruent.
A strong acid is a good proton donor, whereas its conjugate base is a poor proton acceptor.
