Which describes the titration graph when a strong acid is titrated by a weak base? It begins at a low pH and has an equivalence point of 7.
It begins at a low pH and has an equivalence point less than 7.
It begins at a high pH and has an equivalence point of 7.
It begins at a high pH and has an equivalence point greater than 7.

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 answer is a and have a great day
