Answer:
The pH of the solution will be equal to 5.46
Explanation:
The dissociation reaction of HCl is equal to:
HCl → H+ + Cl-
To solve the exercise we must first convert the µmoles to moles using the following conversion factor:
3.5µmoles x [tex]\frac{1 mol}{1x10^{6} umol}[/tex] = 3.5x[tex]10^{-6}[/tex]moles
Assuming a liter of solution, we can calculate the molar concentration by:
M = [tex]\frac{Number of moles}{Liter of solution}[/tex]
Replacing:
M = [tex]\frac{3.5x10^{-6}moles }{1 L}[/tex] = 3.5x[tex]10^{-6}[/tex]moles/L
As this acid dissociates completely, the concentration of protons and chloride will be equal to 3.5x[tex]10^{-6}[/tex]moles/L
The pH will be equal to:
pH = -log[H+]
Replacing:
pH = -log[3.5x[tex]10^{-6}[/tex]] = 5.46
The pH value of reaction solution is 5.46
The acid HCl breaks into hydrogen and chlorine.
HCl ⇒ H⁺ + Cl⁻
As we know that, [tex]3.50\mu mol=3.5*10^{-6} moles[/tex]
The Molarity of solution is,
[tex]M=3.5*10^{-6}moles/liter[/tex]
The pH value is given as,
[tex]pH=-log[H]\\\\pH=-log[3.5*10^{-6} ]\\\\pH=5.46[/tex]
