Respuesta :
The given [tex]H_3O^+[/tex] ion concentration of a solution is an acidic solution and has a pH of 5.
How does the pH scale measure?
- The letters pH stand for the potential of hydrogen since pH is effectively a measure of the concentration of hydrogen ions (that is, protons) in a substance.
- The pH scale measures the relative acidity and alkalinity of solutions.
- It's a negative logarithmic scale of base ten that measures the potential of a solution to accept protons in the form of hydrogen ions.
- A pH scale ranges from 0 to 14 with 7 being neutral.
- A pH lower than 7 is considered acidic and a pH greater than 7 is considered basic (alkaline).
What is the pH value of an [tex]H_3O^+[/tex] ion?
pH can be calculated by using the following equation:
pH = -1(log[H3O+])
Where [H3O+] is the concentration of hydronium ions (hydrogen ions).
The concentration is given as 1 × [tex]10^-^5[/tex] mole per liter.
So, if [H3O+] = 1x[tex]10^-^5[/tex] mol/L,
then the pH = -1(log(1 × [tex]10^-^5[/tex] )) = 5
So, the pH of the given solution is 5. The value is less than 7. Hence it is considered an acidic solution.
Therefore, The given solution is an acidic solution with a pH of 5.
