The pH calculator can determine the pH from H⁺ molar concentration, or Ka, and the concentration of a solution.
This online pH calculator is designed to determine the pH of an aqueous solution of a given chemical compound. You can select any acid or base from the list of chemicals, or use a known value for the dissociation constant K a or K b .
From the source of lumen learning: pH and pOH, ENVIRONMENTAL SCIENCE. An online pH calculator is exclusively designed to calculate pH either from volume, concentration, or weight of the aqueous solution.
Calculate the pH of a solution given the concentration or mass and volume. Plus, learn the formulas to calculate pH and pOH.
Solution is formed by mixing known volumes of solutions with known concentrations. For each compound enter compound name (optional), concentration, volume and Ka/Kb or pKa/pKb values. For example: Compute pH of the 0.1 M solution of acetic acid (pKa=4.76).
These online calculators calculate the pH of a solution. There are two calculators – one for either strong acid or strong base, and another for either weak acid or weak base. Below you can find two calculators that you can use to check answers to chemistry problems.
Find the pH and the related values for any solution using the pH calculator. It can find four values pH, pOH, H+, and OH-. It also tells how the values were computed.
Free online pH calculator for acids, bases and salts. Calculations are based on hydrochemistry program PhreeqC.
To calculate pH, first convert concentration to molarity. The easiest way to perform the calculation on a scientific calculator is to enter the hydrogen ion concentrations, press the log key (not the ln key, which is natural logarithm), and then take the negative of the value.
Calculation: The pH Calculator uses the formula: pH = -log [H⁺]. It takes the logarithm (base 10) of the hydrogen ion concentration and reverses the sign to provide the pH value. pH Result: The tool instantly displays the pH value based on your input. For example, a concentration of 0.01 M would yield a pH of 2. Benefits of Using a pH Calculator:
