First, convert the mass of to moles. Second, calculate the molarity of the solution. Because is a strong base and is soluble, the will be equal to the concentration of the . Third, use to calculate the in the solution. Lastly, calculate the pH.
WebHowever, as the pH of the solution increases (say, by adding base), the carboxylic acid proton is removed, usually at a pH between 2 and 3. In a middle range of pHs, therefore, the amine group is protonated, but the carboxylic acid group has lost the proton. (This is called a zwitterion.) At more basic pH values, the amine proton is dissociated. WebJul 21, 2024 · The formula to calculate pH is: pH = -log [H+] The brackets [] refer to molarity, M. Molarity is given in units of moles per liter of solution. In a chemistry problem, you may …
