Answer:
Concentration of hydrogen ion, [tex][H^+]=5.0118*10^{-6} M[/tex]
Explanation:
pH is defined as the negative logarithm of hydrogen ion's concentration.
The lower the value of pH, the higher the acidic the solution is.
The formula for pH can be written as:
[tex]pH=-log[H^+][/tex]
Given,
pH of the saliva of Marco = 5.3
To calculate: Hydrogen ion concentration in the saliva
Thus, applying in the formula as:
[tex]pH=-log[H^+][/tex]
[tex]5.3=-log[H^+][/tex]
So,
[tex]log[H^+]=-5.3[/tex]
[tex][H^+]=10^{(-5.3)}[/tex]
[tex][H^+]=5.0118*10^{-6} M[/tex]
The measure of the solution depicting the acidity and basicity is called pH. The concentration of the hydrogen ion [tex][\rm H^{+}][/tex] is [tex]5.011 \times 10^{-6} \;\rm M[/tex].
What is pH?
pH is the measure of the hydrogen ion concentration released in the solution that describes the acidic and basic behaviour of the solution. Lower the pH higher will be the concentration of the solution.
The pH of Marco's saliva is 5.3 and the formula for pH is,
[tex]\rm pH= - log [H]^{+}[/tex]
Substituting values in the above formula:
[tex]\begin{aligned} 5.3 &= \rm - log [H]^{+}\\\\-5.3 &= \rm log [H]^{+}\\\\\rm [H]^{+} & = 10^{(-5.3)}\\\\&= 5.0118 \times 10^{-6} \;\rm M\end{aligned}[/tex]
Therefore, The concentration of the hydrogen ion [tex][\rm H^{+}][/tex] is [tex]5.011 \times 10^{-6} \;\rm M[/tex].
