The pH of the solution is the negative logarithm of a proton or the hydrogen ion concentration. The pH of 0.39 M acetic acid solution (CH₃COONa) is 2.58.
<h3>What is pH?</h3>
The pH has been said to be the hydrogen ion concentration that can also be given by the pOH.
Given,
The acid dissociation constant Ka = 1.8 × 10⁻⁵
Concentration of acetic acid (C) = 0.39 M
The hydrogen ion concentration from Ka and molar concentration are calculated as:
H⁺ = √ Ka × C
= √1.8 × 10⁻⁵ × 0.39
= √0.00000702
= 0.0026
Now, pH from hydrogen ion is calculated as,
pH = - log [H⁺]
= - log [0.0026]
= 2.58
Therefore, the pH of acetic acid is 2.58.

Answer:
Why then is carbon dioxide a nonpolar molecule while water is a polar molecule? Carbon dioxide is a nonpolar molecule because its atoms equally share the electrons. Water is polar because its atoms share the electrons unequally.

Plate Tectonics is a theory that shows how the lithospheric plates move and the continents on all of them. As the continents move oceans began to change over time. Just like the way clouds change positions throughout the day.
