On the method of calculating the concentration of hydrogen ions from pH value
The method of calculating the concentration of hydrogen ions from pH value
The method of calculating the concentration of hydrogen ions from pH value is the main point of chemistry.
The definition of pH is the negative logarithm of the concentration of hydrogen ions. In the mathematical formula, it is $pH = -\ log_ {10} [H ^ +] $. In this formula, if you want to find the concentration of hydrogen ions $[H ^ +] $, it can be deformed to $[H ^ +] = 10 ^ {-pH} $.
There is a solution now, and its pH is known to be 3. According to the above method, find the hydrogen ion concentration, then $[H ^ +] = 10 ^ {-3} mol/L $. This is a specific number as an example, indicating that the method of calculating the hydrogen ion concentration from the pH value is also.
Generally, the pH value of acidic solutions is less than 7, and the hydrogen ion concentration is greater than 10 dollars ^ {-7} mol/L $; the pH value of alkaline solutions is greater than 7, and the hydrogen ion concentration is less than 10 dollars ^ {-7} mol/L $; the pH value of neutral ones is equal to 7, and the hydrogen ion concentration is equal to 10 dollars ^ {-7} mol/L $.
From this perspective, the method of calculating the concentration of hydrogen ions from the pH value can help us understand the acidity and alkalinity of the solution, which is very useful in many fields such as chemical experiments and industrial production. You must be familiar with this technique in order to be able to navigate the path of chemistry without hindrance.
