Enter components of the mixture


Instructions for pH Solver

Case 1. Initial concentrations of components in a mixture are known.
For each compound enter compound name (optional), concentration and Ka/Kb or pKa/pKb values. For example:
CH3COOH pKa=4.76 c=0.1
HCl pKa=-10 c=0.1

Case 2. 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:
CH3COOH pKa=4.76 c=0.1 v=10
HCl pKa=-10 c=0.1 v=20

For strong acids enter pKa=-10
For strong bases enter pKb=-10

Example 1
Compute pH of the 0.1 M solution of acetic acid (pKa=4.76).


Example 2
What is the pH of the 10-7 M HCl?


Example 3
Calculate pH and pOH of the solution containging 0.1M of H3PO3 (pKa1=2.12, pKa2=7.21, pKa3=12.67)?


Example 4
What is pH of the solution obtained by mixing 10 ml 0.5 M of C6H5COONa and 20 ml 0.2 M C6H5COOH (pKa=4.21)?
