The PH of a solution of Hcl is 2.what is the amount of acid present in a litre of the solution ​

Explanation:

By DEFINITION… pH , i.e. pouvoir hydrogène , “power of hydrogen” , pH=−log10[H3O+] .

And so if pH=2 , we take REVERSE logarithms..i.e. [H3O+]=10−2∙mol∙L−1 … [H3O+]=0.010∙mol∙L−1 …,

We know that hydrochloric acid, for which the protolysis is complete, undergoes the reaction..

HCl(aq)+H2O(l)→H3O++Cl−

The solution is thus stoichiometric in hydronium ion…

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.
