the concentration of HNO3 in a solution that has a pH of 3.4?
Well, well, well, looks like pH wants to be center stage today! Now, if we're talking about a solution with a pH of 3.4, that means it's definitely on the acidic side of the spectrum. So, to find the concentration of HNO3, we need to utilize the magic of logarithms!
Since pH is defined as the negative logarithm of the concentration of H+ ions, we can rearrange the equation to find the concentration. So, if the pH is 3.4, we can find the concentration using the formula: [H+] = 10^(-pH).
Plug in the numbers, do the calculations (or maybe ask a calculator clown), and voila! You'll have the concentration of HNO3 in your solution. Just remember, my friend, keep those acids away from your funny bone!
To determine the concentration of HNO3 in a solution with a pH of 3.4, you can use the formula for calculating the concentration of hydrogen ions (H+) in a solution.
Step 1: Convert the pH value to the concentration of hydrogen ions (H+).
The pH scale is based on the negative logarithm (base 10) of the concentration of hydrogen ions. The equation to convert from pH to H+ concentration is:
[H+] = 10^(-pH)
Substituting the pH value of 3.4 into the equation:
[H+] = 10^(-3.4)
Using a calculator, you can find that the concentration of hydrogen ions in the solution is approximately 3.98 x 10^(-4) mol/L.
Step 2: Equate the concentration of hydrogen ions to the concentration of HNO3.
HNO3 is a strong acid that dissociates completely into H+ and NO3- ions. This means that the concentration of hydrogen ions is equal to the concentration of HNO3 in the solution.
Therefore, the concentration of HNO3 in the solution with a pH of 3.4 is approximately 3.98 x 10^(-4) mol/L.
To determine the concentration of HNO3 in a solution with a given pH, we can use the concept of pH and acid dissociation. The pH of a solution is a measure of its acidity or basicity, with a lower pH indicating a more acidic solution. Additionally, since HNO3 is a strong acid, it is completely dissociated in water.
First, we need to understand the relationship between pH and the concentration of hydrogen ions (H+) in a solution. The pH scale is logarithmic, meaning that a change of one pH unit corresponds to a tenfold change in the concentration of H+. The formula for pH is:
pH = -log[H+]
Given that the pH of the solution is 3.4, we can write it in terms of the hydrogen ion concentration:
3.4 = -log[H+]
To continue, we can rearrange the equation as follows:
[H+] = 10^(-pH)
Now, we can calculate the concentration of H+ in the solution using its pH value:
[H+] = 10^(-3.4)
Using a calculator or mathematical software, we find that [H+] ≈ 4.0 x 10^(-4) M (mol/L).
Since HNO3 dissociates completely, the concentration of HNO3 is equal to the concentration of H+ in the solution. Therefore, the concentration of HNO3 in the given solution is approximately 4.0 x 10^(-4) M.
pH = -log (H^+)
-3.4 = log (H^+)
3.98E-4 M = (H^+)
