Determine the ph
[H30+] = 4.8×10^-3 M
Express your answer using two decimal places.
The pH can be determined using the formula: pH = -log[H3O+]
Substituting the given value:
pH = -log(4.8x10^-3)
pH = -(-2.32)
pH = 2.32 (rounded to two decimal places)
Thus, the pH is 2.32.
The pH is a measure of the acidity or alkalinity of a solution and is defined as the negative logarithm (base 10) of the hydronium ion concentration, [H3O+].
To determine the pH, we can use the following formula:
pH = -log10([H3O+])
Substituting the given value of [H3O+] = 4.8×10^-3 M into the formula, we can calculate the pH:
pH = -log10(4.8×10^-3)
Using a calculator, we find:
pH ≈ 2.32
Therefore, the pH of the solution is approximately 2.32.
To determine the pH given the concentration of H3O+ ions, you can use the formula:
pH = -log[H3O+]
In this case, the concentration of H3O+ ions is given as 4.8×10^-3 M. So, we can plug this value into the formula to calculate the pH:
pH = -log(4.8×10^-3)
To solve this, you can use a scientific calculator or the logarithmic function on your calculator.
Taking the logarithm of 4.8×10^-3, we get -2.32.
Therefore, the pH is -(-2.32) = 2.32.
Expressing the answer using two decimal places, the pH is 2.32.
