One or more unwanted ionic pollutants are eliminated from water using the ion exchange technique by exchanging them with a less disagreeable or non-objectionable ionic material.
The engineers of ion exchange products need to know which items are soluble so that the the pollutant can be extracted from the water by dissolving the ionic pollutant in a suitable solvent or exchange product. In order to identify the solvent, the engineer must be aware of the physical and chemical properties of the pollutant.
The exchanged material and the contaminant both need to be dissolved and have the same kind of electrical charge (positive or negative). A common instance of ion exchange is the "water softening" procedure, which lowers the amount of calcium and magnesium in the water.

Answer: Anchoring and Adjustment bias
Explanation:
ANCHORING AND ADJUSTMENT bias refers to a situation where individuals base their decisions on one point and make changes driven by that point.
This point is the starting point and is usually known as an ANCHOR and is adjusted until an acceptable value is reached which is rarely the case and is especially a problem when the anchor is quite different from the true answer.
