PLEASE HELP A 60mL HCl solution is titrated with 25mL of a 0.60M KOH solution. What is the concentration of the HCl solution?

1) 2.5 mol/L
2) 0.65 mol/L
3) 1.56 mol/L
4) 0.25 mol/L

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.
