Which one of the following is correct for a solution in which [H+] = 1...
Explanation:
The concentration of hydrogen ions, denoted as [H+], is a measure of the acidity or basicity of a solution. A solution with a high concentration of hydrogen ions is acidic, while a solution with a low concentration of hydrogen ions is basic.
In this case, the concentration of hydrogen ions is given as [H+] = 10^-8 M.
Concentration of Hydrogen Ions:
The concentration of hydrogen ions in a solution is determined by the pH scale. The pH scale is a logarithmic scale that ranges from 0 to 14, with 0 being highly acidic, 7 being neutral, and 14 being highly basic.
To determine the pH of a solution, we take the negative logarithm (base 10) of the hydrogen ion concentration. Mathematically, pH = -log[H+].
Calculating the pH:
In this case, the concentration of hydrogen ions is [H+] = 10^-8 M. Taking the negative logarithm of this concentration, we have:
pH = -log(10^-8) = -(-8) = 8
Therefore, the pH of the solution is 8.
Determining the Acidity or Basicity:
A solution with a pH of 8 is considered basic. The pH scale ranges from 0 to 14, with pH values less than 7 being acidic, pH values greater than 7 being basic, and pH 7 being neutral.
Therefore, the correct answer is option C: 8, basic.
