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.

The a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.
What is pressure gauge?
A device used to measure a fluid's (liquid or gas') state by calculating the force the fluid would apply to a unit area if it were at rest.
What is pressure?
The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables.
Therefore, a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.
