12 a buffering solution is made from acetic acid (ch, co2h) and its conjugate base (ch3002 7. which reaction describes the buffering effect of the solution when an acid is
added to the solution?
ch, co2 (aq) + h+ (aq) + ch3coh(aq)
ch, co, h(aq) + oh(aq) - ch3c02"(aq) + h2o()
ch3co2 (aq) + h20(1) -- ch3co2h(aq) + oh(aq)
ch, co2h(aq) -- ch3c02 (aq) + h*(aq)

Answer is (d)a brainliest would be appreciated

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.
