Below are some of the steps completed in the titration process.

(i) add base from the buret to the acid.
(ii) transfer a known volume of acid to an erlenmeyer flask.
(iii) add three drops of chemical indicator to the acid.
(iv) position the erlenmeyer flask under the buret.

which lists the steps in the correct order of occurrence?

The given process is that of an acid-base titration where the base is taken in the burette and is being titrated against an acid taken in a flask. The steps in the correct order are:

1) Transfer a known volume of acid to an Erlenmeyer flask.

2) Add three drops of chemical indicator to the acid.

3) Position the Erlenmeyer flask under the buret.

4) Add base from the buret to the acid.

Ans: ii) , iii), iv) and i)

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.
