HCN Is a weak acid that dissociates in water. Which statement is completely true?

a) HCN is the Bronsted-Lowry base in this problem

b) HCN is a conjugate acid in this problem

c) with a Ka value, HCN is a strong acid

d) CN^-1 ion is its conjugte base

e)HCN solutions have a pH value near 11

Expert Solution

HCN gives H+

So, it is a Bronsted-Lowry acid

Its conjugate base is CN-

since it is acid, its solution will have pH of less than 7

Answer: d

1. The degree to which a weak base dissociates is given by the base-ionization constant, Kb. For the generic weak base, B B(aq)+H2O(l)⇌BH+(aq)+OH−(aq) this constant is given by Kb=[BH+][OH−][B] Strong bases will have a higher Kb value. Similarly, strong bases will have a higher percent ionization value. Percent ionization=[OH−] equilibrium[B] initial×100% Strong bases, for which Kb is very large, ionize completely (100%). For weak bases, the percent ionization changes with concentration. The more dilute the solution, the greater the percent...
