Question

Write the${\mathrm{K}}_{\mathrm{b}}$reaction for pyridine and for sodium 2-mercaptoethanol.

Short answer

The${\mathrm{K}}_{\mathrm{b}}$reaction for pyridine is written as The ${\mathrm{K}}_{\mathrm{b}}$reaction for sodium 2-mercaptoethanol is written as

${\mathrm{HOCH}}_2{\mathrm{S}}^{-}{\mathrm{Na}}^{+}+{\mathrm{H}}_2\mathrm{O}\rightleftharpoons {\mathrm{HOCH}}_2{\mathrm{CH}}_2\mathrm{SH}+\mathrm{NaOH}$

Step-by-step solution

Define base dissolution constant

The base dissociation constant (${\mathbf{K}}^{\mathbf{b}}$) is a metric for basicity, or the strength of the base in general.

Write the Kbreaction

The base dissociation constant ${\mathrm{K}}_{\mathrm{b}}$comes when base is reacted with weak acid such as water that gives weak acid.

The ${\mathrm{K}}_{\mathrm{b}}$reaction for pyridine is,

The${\mathrm{K}}_{\mathrm{b}}$reaction for sodium 2-mercaptoethanol is,

${\mathrm{HOCH}}_2{\mathrm{S}}^{-}{\mathrm{Na}}^{+}+{\mathrm{H}}_2\mathrm{O}{\mathrm{HOCH}}_2{\mathrm{CH}}_2\mathrm{SH}+\mathrm{NaOH}$
