What is the reason for the low solubility of lif (0.27 g
per100 ml h2o) compared to csf(367 g per 100 ml h2o)?
a) the high solvation energy for

b) the strong ionic bond in lif
c) the high solvation energy for

d)the high solvation energy for

also, what does solvation energy mean
'mconfused.

The answer is C. The high solvation energy for LI+

Explanation:

LiF has lower solubility because of the high solvation energy of Li+ ion. This is due to the smaller  size and very big charge compared to Cs+ ion which has a bigger size and solvent molecules easily surround it.

Solvation energy is simply the amount energy that is required to make a solute dissolve in a solvent.

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.  

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots
