Determine the MAX amount of titrant you will possibly need for your titration.
Your unknown solution has been prepared by dissolving btw 0.05-0.09mol of zwitterion form of the amino acid in 1L of ~ 0.1M HCl solution.
you will titrate 50mL of that amino acid with 0.5M NaOH.
Assume that the amino acid concentration of 0.0900mol per L of 0.1 M HCl
Please help me...I don't uderstand what to do. Explanation will help greatly.
