# How Does NaOH Affect the Degree of Dissociation of Triethylamine?

• Krushnaraj Pandya
In summary, the ionization constant of {(C_2 H_5)}_3 {N} is 6.4 x 10^(-5). When mixed with 0.01 M NaOH solution, the degree of dissociation in its 0.1 M solution is calculated to be 6.4 x 10^(-3). The book's answer is also 6.4 x 10^(-3).

## Homework Statement

The ionization constant of ## {(C_2 H_5)}_3 {N}## is 6.4 x 10^(-5). Calculate degree of dissociation in its 0.1 M solution when it is mixed with 0.01 M NaOH solution.

2. The attempt at a solution
the compound gives ##{(C_2 H_5)}_3 {NH+}## and ##OH-##. C is initial concentration of compound=0.1 M and x as degree of dissociation- C*x is final concentration of ##{(C_2 H_5)}_3 {NH+}## and since NaOH is strong electrolyte 0.01 M OH- is present. Since x is small compared to 0.01 we take OH concentration as 0.01. Now (C*x)(0.01)=K. placing 0.1 as C we get x as 6.4 x 10^(-2). However the answer is 6.4 x 10^(-3). Where am I wrong?

Never mind. I totally forgot to write C in denominator. Silly me.

You are saying you now get the same answer as the book? I got the same answer so the book appears to be right. Question phrasing a bit loose.

yes, I did- thank you. I was just making a really silly mistake.

## 1. What is ionic concentration?

Ionic concentration refers to the measure of the amount of ions present in a solution. It is usually expressed in moles per liter (M) or millimoles per liter (mM).

## 2. How is ionic concentration calculated?

Ionic concentration can be calculated by dividing the number of moles of ions present in a solution by the volume of the solution in liters.

## 3. Why is ionic concentration important?

Ionic concentration is important because it affects the properties and behavior of a solution. It can determine the strength of an acid or base, the conductivity of a solution, and the solubility of compounds.

## 4. What factors can affect ionic concentration?

The factors that can affect ionic concentration include temperature, pressure, and the presence of other ions or molecules in the solution.

## 5. How can ionic concentration be adjusted?

Ionic concentration can be adjusted by diluting a solution with water or by adding solutes to a solution. It can also be controlled by changing the temperature or pressure of the solution.
