Calculate the ph of a buffer solution made from 0.10 m nh3 and 0.10 m nh4cl
salt. kb = 1.8 x 10-5

b. calculate the ph of the buffer in part a, after 12 ml of 0.20 m hcl is added to 125 ml
of the buffer in part a.

c. calculate the ph when 12 ml of 0.20 m hcl added to 125 ml of water. how does
the ph compare to the ph found in part b?

B. a graduated substance

B.) falsehope this !

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
