You are using a standardized 0.1250 M solution of sodium hydroxide to determine the concentration of sulfuric acid. After pipetting 10.00 mL of the H2SO4 into your flask you find that you use 19.22 mL of your NaOH solution to reach the endpoint. No, wait... I mean What is the concentration of the sulfuric acid? H2SO4 + 2NaOH ---> Na2SO4 + 2HOH

Thus the concentration of the sulfuric acid is 0.1201 M

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is NaOH.

We are given:

Putting values in above equation, we get:

Thus the concentration of the sulfuric acid is 0.1201

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.
