What is the pH of a solution with [H+] = 1.25 x 10^-10 M?
Calculating pH of a Solution
Answer: The pH of a solution is 9.903
Explanation:
Given data:
Concentration of hydrogen ion, [H+] = 1.25 x 10^-10 M
pH: pH is defined as the negative logarithm of the hydrogen ion concentration.
Formula used:
pH = -log[H+]
Now, let's calculate the pH of the solution:
pH = -log(1.25 x 10^-10)
pH = 9.903
Therefore, the pH of a solution with [H+] = 1.25 x 10^-10 M is 9.903.
What is the significance of pH in determining the acidic or basic nature of a solution? pH plays a crucial role in determining the acidity or basicity of a solution. A solution with a pH below 7 is considered acidic, while a solution with a pH above 7 is considered basic. A pH of 7 indicates a neutral solution. The pH scale is logarithmic, meaning each unit change in pH represents a tenfold change in hydrogen ion concentration. Lower pH values indicate higher hydrogen ion concentrations and stronger acidity, while higher pH values indicate lower hydrogen ion concentrations and stronger basicity.
