Answer:
Lithium nitrate
Explanation:
Lithium nitrate is an inorganic compound with the formula LiNO3. It is the lithium salt of nitric acid (an alkali metal nitrate).
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.
