Interpretation Introduction

Interpretation:

The pH of a 0.22 M solution of pyridinium ion (C5H6NH+) has to be calculated

Concept Information:

  • Salt hydrolysis is a reaction in which the ion of salt reacts with water and produce either hydronium ion or hydroxide ion.
  • In other words, when an ionic compound bearing a weak acid as its cation; undergoes hydrolysis while dissolved in water. The weak acid cation, donates a proton from water and produce its conjugate base and hydronium ion.
  • For Example: The dissociation of salt NH4Cl gives, NH4+ and Cl- ions. The ions of NH4Cl reacts with water and produce hydronium ions, which impacts the pH of the solution.

NH4+(aq)+H2O(l)NH3(aq)+H3O+(aq)

Relationship between Ka and Kb

Ka×Kb=Kw

Relationship between pH and pOH:

pH + pOH = 14

To Calculate: The pH of a 0.22 M solution of pyridinium ion (C5H6NH+)
