What is the concentration of each ion in 0.250 M Na2SO4?

The concentration of is 0.500 M and is 0.250 M in 0.250 M

Explanation:

The dissociation of is given as:

As 1 mole of gives  = 2 moles of

0.250 moles of gives = moles of

As 1 mole of gives = 1 mole of

0.250 moles of gives = moles of

Thus the concentration of is 0.500 M and is 0.250 M in 0.250 M

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.
