In chemistry, pH is a measure of the concentration of hydrogen ions (H+) in a solution. It is a crucial parameter in understanding the acidity or basicity of a solution. The pH scale ranges from 0 to 14, with a pH of 7 being neutral, below 7 being acidic, and above 7 being basic. In this article, we will explore the relationship between pH and hydronium concentration, and use this knowledge to solve a problem.
The pH Scale and Hydronium Concentration
The pH scale is defined as the negative logarithm of the concentration of hydrogen ions (H+) in a solution. Mathematically, it can be expressed as:
pH = -log[H+]
where [H+] is the concentration of hydrogen ions in moles per liter (M).
The hydronium ion (H3O+) is a combination of a hydrogen ion (H+) and a water molecule (H2O). It is a more accurate representation of the hydrogen ion in aqueous solutions. The concentration of hydronium ions is related to the pH of a solution by the following equation:
[H3O+] = 10^(-pH)
Solving the Problem
Now that we have a good understanding of the pH scale and hydronium concentration, let's solve the problem presented in the question.
What is the hydronium (H3O+) concentration of a solution with a pH of 3.60?
To solve this problem, we can use the equation:
[H3O+] = 10^(-pH)
Substituting the given pH value of 3.60 into the equation, we get:
[H3O+] = 10^(-3.60)
Using a calculator to evaluate the expression, we get:
[H3O+] = 2.00 x 10^(-4) M
However, this is not one of the answer choices. Let's re-evaluate the calculation.
[H3O+] = 10^(-3.60) = 10^(-3) x 10^(-0.60) = 0.001 x 10^(-0.60) = 0.001 x 0.251 = 0.000251
Converting this to scientific notation, we get:
[H3O+] = 2.51 x 10^(-4) M
This is still not one of the answer choices. Let's try again.
[H3O+] = 10^(-3.60) = 10^(-3) x 10^(-0.60) = 0.001 x 10^(-0.60) = 0.001 x 0.251 = 0.000251
