Calculation of Hydrogen Ion Concentration
To calculate the hydrogen ion concentration of a 10^-8M HCl aqueous solution at 298K, we need to use the equation for the ion product constant of water:
Kw = [H+][OH-] = 10^-14
Since HCl is a strong acid, it dissociates completely in water to form hydrogen ions and chloride ions. Therefore, the hydrogen ion concentration of the solution is equal to the initial concentration of HCl:
[H+] = 10^-8M
Substituting this value into the equation for Kw:
10^-14 = (10^-8M)[OH-]
Solving for [OH-]:
[OH-] = 10^-6M
Since the solution is neutral, the hydrogen ion concentration must be equal to the hydroxide ion concentration:
[H+] = [OH-] = 10^-6M
Therefore, the correct answer is A) 10^-6.
Explanation
- The question asks us to calculate the hydrogen ion concentration of a 10^-8M HCl aqueous solution at 298K.
- To solve the problem, we need to use the equation for the ion product constant of water, which relates the concentrations of hydrogen ions and hydroxide ions in a neutral solution.
- Since HCl is a strong acid, it dissociates completely in water to form hydrogen ions and chloride ions. Therefore, the hydrogen ion concentration of the solution is equal to the initial concentration of HCl.
- Substituting the values into the equation for Kw, we can solve for the hydroxide ion concentration.
- Since the solution is neutral, the hydrogen ion concentration must be equal to the hydroxide ion concentration.
- Therefore, the correct answer is A) 10^-6.
