Why does the salt reappear when the water evaporates??

Salt particles move about the water. Each particle is surrounded by water molecules.The water particles (molecules) keep the salt particles from rearranging themselves back into a salt crystal. Salt particles are carried throughout the solution surrounded by water particles.

As the water evaporates less and less water molecules are present to keep the salt particles apart. The salt therefore recrystalises and can be collected.

-B

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
