The equation you provided appears to represent a chemical reaction involving cyanide ions (CN⁻) and water (H₂O), resulting in the formation of hydrogen cyanide (HCN) and hydroxide ions (OH⁻). In this process, the cyanide ion interacts with water, leading to the release of HCN and the production of hydroxide. This reaction can be understood as a hydrolysis of the cyanide ion, where it accepts a proton from water.

What are the acids in the following equilibrium reaction cn- plus h2o hcn plus oh?
The acid in the reaction is hydrogen cyanide (HCN), which is formed when cyanide ion (CN-) reacts with water (H2O) to release hydroxide ion (OH-).
What is Kb for CN-(aq) H2O(l) HCN(aq) OH-(aq)?
The base dissociation constant ((K_b)) for the cyanide ion ((CN^-)) can be derived from the equilibrium expression for its reaction with water: (CN^- + H_2O \rightleftharpoons HCN + OH^-). The (K_b) value can be calculated using the relationship (K_b = \frac{K_w}{K_a}), where (K_w) is the ion product of water (1.0 x (10^{-14}) at 25°C) and (K_a) is the acid dissociation constant for hydrogen cyanide (HCN). Given that (K_a) for HCN is approximately (6.2 \times 10^{-10}), you can substitute this value into the equation to find (K_b). Thus, (K_b \approx \frac{1.0 \times 10^{-14}}{6.2 \times 10^{-10}} \approx 1.61 \times 10^{-5}).

The Kb for CN- (aq) is the equilibrium constant for the reaction of CN- with water to form HCN (aq) and OH- (aq). It represents the strength of the base CN- in solution. It can be calculated by taking the concentration of the products (HCN and OH-) and dividing by the concentration of CN- at equilibrium.

NH3 + H20 <----> NH4+ + OH- Ammonia is a weak base so it is the favored side of the equilbrium. Conjugate acid and base pairs only differ by a proton. So ammonia and ammonium are pairs and water and hydroxide ions are pairs. NH4+ + CN- <-------> HCN + NH3
