Calculate the concentrations of all ionic species in a 0.25 M solution of histidine at pH...
Calculate the concentrations of all ionic species in a 0.25 M solution of histidine at pH 2, pH 6.4, and pH 9.3.
I have zero idea how to do this so can someone thoroughly explain. My book just gives the the pka of histidine as 6. What do i do to solve this, please help!
