Question

what is the ph of a solution that has an h concentration of: 1.75 x 10-5 mol/l 6.50 x 10-10 mol/l 1.0 x 10-4 mol/l 1.50 x 10-5 mol/l

Answer 1

To calculate the pH of a solution, you take the negative base-10 logarithm of the hydrogen ion concentration ([H+]). The question requires calculation of pH for various given [H+] levels, determining the acidity or basicity of the solutions.

Step-by-step explanation:

The question involves calculating the pH of solutions given their hydrogen ion concentration ([H+]). The pH of a solution is found by taking the negative base-10 logarithm (-log) of the hydrogen ion concentration. Using this formula, let's calculate the pH for the given concentrations:

For [H+] = 1.75 x 10-5 M, pH = -log(1.75 x 10-5)

For [H+] = 6.50 x 10-10 M, pH = -log(6.50 x 10-10)

For [H+] = 1.0 x 10-4 M, pH = -log(1.0 x 10-4)

For [H+] = 1.50 x 10-5 M, pH = -log(1.50 x 10-5)

Each pH value indicates the acidity or basicity of the solution. A pH lower than 7.0 indicates an acidic solution, while a pH higher than 7.0 indicates a basic solution.
