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.

If you are alerted that a tsunami is approaching, your first reaction should be to immediately head for a location as high above sea level as possible.
A sequence of massive ocean waves known as a tsunami can be brought on by earthquakes, underwater landslides, volcanic eruptions, or asteroids. As the waves come in and go out, a tsunami can kill, hurt, or destroy people as well as harm or destroy structures and infrastructure. If an earthquake is strong enough to induce sudden and significant displacement of a significant amount of water, along with severe movement of the ground, it will result in a tsunami.
It's crucial that you comprehend natural signals because there might not always be enough time for an official warning. A tsunami may occur if you are near the shore and experience a large or prolonged earthquake, notice a dramatic rise or decrease in the ocean, or hear a loud roar from the water. This is a warning to you. Move to a safe place and take action. Waiting for official orders is not advisable.
