5. The pH of a solution is 4. Which of the following is correct?
(A) The solution is basic with an [OH-] of 1 x 10-4
(B) The solution is acidic with a pH of 10
(C) The solution is acidic with a pOH of 10
(D) The solution is basic with a pOH of 4

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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
