Hi,
well my friend is in the final year graduation and he is working on a project a part of it is trying to detect the pH of a certain compound exist in acidic HCl solution, this compund don't remember its name for recent but it has the amino 'NH2" group this compund is in solution of HCL and he wants to detect the pH of the compound containing the amino group ONLY , but the problem is that HCl would alter the pH calculation raising it..so how can he detect a ph of the amino gp located in hcl solution without the conflicting of HCl in his calculations for the amino? he was thinking about neutralizing the HCl with NaOH so that effect of HCl is canceled but the problem is that this method sometimes is inaccurate and cause some errors..so is there any compound to be added so that it can let's say 'shield' the Hcl cancelling its effect on the ph?
thanks in advance
