###### FREE Expert Solution

For this problem, we are being asked to calculate the pH, H+, and OH- concentration of 0.40 M Aniline

Establish the Kb expression of the dissolution of aniline and determine the pH using an ICE chart

We will solve this problem through these steps:

Step 1: Write an equation for the dissociation of aniline

Step 2: Write an expression for the Kb

Step 3: Set up an ICE table to calculate the OHion concentration.

Step 4: Calculate the pH of solution using OH- ion concentration.

Step 1: Dissociation of aniline in solution.

NaHCOO is a weak base and dissociates partially in aqueous solution.

C6H5NH2 (aq) + H2O(l) C6H5NH3+ (aq) + OH-(aq)                Kb = 3.8x10-10

Step 2: Kb expression for NaHCOO

The expression of Kb can be written like the equilibrium expression:

Solids and liquids are not included in equilibrium expressions.
