Calculate ph value of soft drink having hydrogen ion concentration equal to 3x10^-5.
See your double post below.
To calculate the pH value of a solution, you can use the formula:
pH = -log[H+]
where [H+] represents the hydrogen ion concentration.
In this case, the hydrogen ion concentration is given as 3x10^-5.
Therefore, to calculate the pH value:
1. Take the negative logarithm (base 10) of the hydrogen ion concentration:
pH = -log(3x10^-5)
2. Solve the logarithm using the positive exponent:
pH = -log(3) + log(10^-5)
3. Apply the logarithm properties:
pH = -log(3) - 5
4. Use a calculator to evaluate the logarithm:
pH ≈ -0.4771 - 5
5. Add the results:
pH ≈ -5.4771
Therefore, the pH value of the soft drink is approximately -5.4771. Note that pH values are typically between 0 and 14, so a negative pH value like this is not physically possible. It is likely that there was an error in the calculations or in the provided hydrogen ion concentration.
