Answer: Option (d) is the correct answer.
Explanation:
When salt is added to water then the sodium and chlorine ions dissociate.
After the dissociation, both the positive and negative ions that is the sodium and chlorine ions will be surrounded by the water molecules. Thereafter, the positive part of water molecule will be attracted to the negative ions that is the chlorine ions and vice versa.
As sodium ion is a cation so it will hold a positive charge, and chlorine ion is an anion so it will hold a negative charge.
Thus, it can be concluded that when salt is added to water, all of the above will happen except option (d) that is the salt breaks into positive chlorine ions and negative sodium ions.
Commonly the sea walls are used for preventing damage from tsunami. A special type of device is also used for detecting the tsunami called floating device.
<h3>
What are the technologies that could help reduce the damage from a tsunami?</h3>
Commonly seawalls are used for preventing damage from tsunamis. There is a network which is used for detecting the earthquake and tsunami and that network is known as Seismological network. This network helps the people to know about the earthquakes and tsunamis and reduces the damages of earthquakes and tsunamis.
The engineers also design a special type of special buoys which is also known as floating devices, these devices are placed near the coastal areas from where the tsunamis can be detected easily.
So we can conclude that commonly the sea walls are used for preventing damage from tsunami. A special type of device is also used for detecting the tsunami called floating device.
