What is a pH Calculator?
The pH level calculator is an online tool to find the pH of a solution. It has different parameters such as molarity, concentration, and H+ ion concentration. An online pH concentration calculator automatically calculates the pH of the acid or base you input.
The pH formula calculator is a beneficial tool for students, researchers, professionals, or anyone who needs it. It is used in various fields where finding the acidity or alkalinity of solutions is important. The concentration of solutions is also important to measure which can be easy for you if you use our molarity solution calculator.
Definition of pH?
pH is the numerical measure of the acidity or alkalinity of a solution. It is usually measured on a pH scale. The scale measured from 0 to 14. The pH of the neutral solutions equals 7. The acidic solution has a pH lower than 7 while the alkaline solution has a pH of more than 7. It is also defined as the negative logarithm of hydrogen ions.
pH = -log [H+]
For buffer solution, the formula of pH is:
pH = pKa + log [salt] / [acid or base]

How do you calculate pH?
We can calculate pH by using the pH scale. It is an easy way to find the pH of a solution. We can calculate pH manually and by using a pH calculator. Right now we are going to tell you how to calculate pH manually. Here are some examples to help you know that:
Example 1:
Find the pH of a solution where 0.09 molar acetic acid and 0.11 molar CH3COONa are present. The Ka for CH3COOH is 1.85 x 10-5.
Solution:
CH3COONa = 0.11 M
CH3COONa = 0.09 M
Ka of CH3COOH = 1.85 x 10-5
pK = -log (1.8 x 10-5) = 4.75
Putting the given data of CH3COONa in the formula
pH = 4.74 + log [0.11] / [0.09]
pH = 4.74 + 0.087 = 4.83
Related: To determine the molar ratio of acetic acid or CH3COONa try our calculator for mole fraction.
Example 2:
What will be the concentration of soil solution if the moist soil has a pH of 7.84?
Solution:
pH of moist soil = 7.84
According to the formula of pH and putting the given data in it,
7.84 = -log [H+]
[H+] = log [7.84]
[H+] = 1.45 x 10-8 M
Suggested: To determine the solution of moist soil, use our molality formula calculator.
