Answer: The pH will be 3.87
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
[tex]pH=-\log [H^+][/tex]
[tex]HCl\rightarrow H^++Cl^{-}[/tex]
According to stoichiometry,
1 mole of [tex]HCl[/tex] gives 1 mole of [tex]H^+[/tex]
Thus [tex]0.000134[/tex] moles of [tex]HCl[/tex] gives =[tex]\frac{1}{1}\times 0.000134=0.0001342[/tex] moles of [tex]H^+[/tex]
Putting in the values:
[tex]pH=-\log[0.000134][/tex]
[tex]pH=3.87[/tex]
Thus the pH will be 3.87
Answer: The pH of 0.000134 M solution of HCl is 3.873.
Explanation:
When HCl dissociates in water then it will give hydrogen and chlorine ions. The reaction will be as follows.
[tex]HCl \rightarrow H^{+} + Cl^{-}[/tex]
This means that 1 mole of HCl is giving 1 mole of hydrogen ions on dissociation.
Hence, pH of the given solution will be calculated as follows.
pH = [tex]-log [H^{+}][/tex]
= [tex]-log (0.000134)[/tex]
= 3.873
Thus, we can conclude that the pH of 0.000134 M solution of HCl is 3.873.
