WebMar 16, 2024 · Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L. Calculate pH by using the pH to H⁺ formula: \qquad \small\rm pH = -log (0.0001) = 4 pH = −log(0.0001) = 4 Now, you can also easily determine pOH and a concentration of hydroxide ions using the formulas:
WebJul 15, 2024 · In carburizing molten salts, the salts consist of a mixture of barium chloride and sodium cyanide. Concentration of sodium cyanide is on the order of 30-35 percent [4].
