Interpretation : The concentrations of hydrogen ion and hydroxide ion in pure water at room temperature is to be explained.
Concept Introduction : The negative logarithm of the concentration of hydrogen ions is the pH of a solution. The values from 0 to 14 are the range of a pH scale.
Answer to Problem 60A
The concentration of hydrogen ion and hydroxide ion in pure water at room temperature are
Explanation of Solution
The formula to calculate pH is given as
Here,
Acidic solutions have pH values below 7.0.
A pH of 7.0 indicates a neutral solution.
ph greater than 7.0 designates a basic solution.
Pure water at
To calculate the hydrogen ion concentration, rearrange the formula:
At neutral pH, the concentration of hydrogen ion and hydroxide ion will be the same.
So, the concentration of hydroxide ion is
