 #### pH Calculator - Calculates pH of a Solution

 Enter components of a solution to calculate pH pKw: Instructions for pH Calculator 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=0.1HCl 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=-1 For strong bases enter pKb=-1 Example 1 Compute pH of the 0.1 M solution of acetic acid (pKa=4.76). CH3COOH pKa=4.76 c=0.1 Example 2 What is the pH of the 10-7 M HCl? HCl pKa=-10 c=1e-7 Example 3 Calculate pH and pOH of the solution containging 0.1M of H3PO4 (pKa1=2.12, pKa2=7.21, pKa3=12.67)? H3PO4 c=0.1 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)? C6H5COOH c=0.2 v=20 pKa=4.21 C6H5COONa c=0.5 v=10 pKb=9.79 Give us feedback about you experience with pH Solver.   Related: Ka Kb pKa pKb Converter
