WebFormula to calculate pH from molarity. To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). Example: Find the pH of a 0.0020 M HCl solution. Since we know that HCl is a strong acid and is 100% ionized in water, therefore; Thus, the pH of the acid is 2.7. WebTo find x we need to solve the quadratic equation and pick the positive root. Finally, plug x into the pH formula to find the pH value. The same applies to bases, where you use the base dissociation constant Kb. Ka and Kb are usually given, or can be found in tables. You may notice that tables list some acids with multiple Ka values. cheer shoes black https://skayhuston.com
