What is the purpose of a histogram?
to provide a visual of the data in a bar graph that has no gaps, so that one can make decisions
to provide the data in dots, so that one can make decisions
to provide the data in a box and whisker, so that it looks like a cat
none of the choices are correct.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
