Hydrocyanic acid, HCN, is a stronger acid than ammonium ion, NH4+. When hydrocyanic acid reacts with ammonia,?

NH3, what species are present in the solution in the largest amount?

hydrocyanic acid and ammonia, HCN and NH3
hydrocyanic acid and ammonium ion, HCN and NH4+
cyanide ion and ammonia, CN- and NH3
cyanide ion and ammonium ion, CN- and NH

Answer:
when hcn and nh3 mix it produces a highly toxic gas that can cause respiratory problems,blindness and even death.
Cyanide and ammonia.

HCN + NH3 = NH4(+) + CN(-)

The reaction lies in favor of the weaker acid (ammonium ion) and the weaker base (cyanide, the conjugate acid of the stronger acid)
