Re: How do I calculate the concentration of a weak base from PH « Reply #1 on: December 03, 2019, 04:55:08 AM » That equation is an approximation that applies only when the degree of ionisation is small.Suppose the degree of ionisation is x. Then the concentration of free base...
Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen i
