To calculate the hydroxide ion (OH-) concentration from the pH value:
\[ [\text{OH}^-] = 10^{-14 + \text{pH}} \]
Where:
OH- concentration is a measure of the amount of hydroxide ions present in a solution. It is an important parameter in chemistry, particularly in the context of acid-base reactions and pH. The concentration of OH- ions in a solution determines its basicity and is inversely related to the concentration of hydrogen ions (H+), which determines acidity.
Let's assume the following value:
Using the formula:
\[ [\text{OH}^-] = 10^{-14 + 7} = 10^{-7} \approx 0.0000001 \, \text{mol/L} \]
The OH- Concentration is approximately 0.0000001 mol/L.
Let's assume the following value:
Using the formula:
\[ [\text{OH}^-] = 10^{-14 + 9} = 10^{-5} \approx 0.00001 \, \text{mol/L} \]
The OH- Concentration is approximately 0.00001 mol/L.
