Final answer:
The i.e.p of a substance refers to the pH at which it has no net electrical charge. If the i.e.p is independent of the electrolyte strength, it means the pH at which the substance is electrically neutral does not depend on the concentration of the electrolyte.
Step-by-step explanation:
In chemistry, the term i.e.p refers to the isoelectric point, which is the pH at which a molecule or a surface has no net electrical charge.
The electrolyte strength refers to the ability of an electrolyte to conduct electricity. If the i.e.p of a substance is independent of the electrolyte strength, it means that the pH at which the substance is electrically neutral does not depend on the concentration of the electrolyte.
