Interpretation Introduction

Interpretation: The process of precipitation of hemoglobin out of the solution at $\text{pH 5}\text{.5}$ , when one had $\text{1 M HCl and 1 M NaOH}$ needs to be explained.

Concept introduction:The isoelectric point of a protein is the pH at which there is an equal number of positive and negative charges (the protein has no net charge). At any pH above the isoelectric point, the protein molecules have a net negative charge; at any pH below the isoelectric point, they have a net positive charge
