Final answer:
To find the molar concentration of a nitric acid solution with a pH of 1.75, you can use the pH formula (pH = -log[H+]) to calculate the hydrogen ion concentration. This results in a molar concentration of approximately 1.78 × 10^-2 M.
Step-by-step explanation:
To find the molar concentration of the nitric acid solution with a pH of 1.75, we need to understand that pH is the negative logarithm (base 10) of the hydrogen ion concentration [H+]. The formula to calculate pH is:
pH = -log[H+]
Calculating the concentration from pH:
- First, we rewrite the pH equation: [H+] = 10-pH.
- Next, we substitute the pH value: [H+] = 10-1.75.
- Perform the calculation: [H+] ≈ 1.78 × 10-2 M.
So, the molar concentration of the nitric acid solution with a pH of 1.75 is approximately 1.78 × 10-2 M.
