If the pH of a solution is 2.7 what is the pOH

pH + pOH = 14 => pOH = 14 - pH = 14 - 2.7 = 11.3

Explanation:

The answer to your question is pOH = 11.3

Explanation:

Data

pH = 2.7

pOH = ?

pH measures the hydronium concentration [H₃O⁺]. The scale of pH goes from 0 to 14. If the solution has a pH from 0 to 6.9 the solution is an acid, if the pH = 7, the solution is neutral and if the pH goes from 7.1 to 14 the solution is an alkali,

Formula

                    pH + pOH = 14

-Solve for pOH

                   pOH = 14 - pH

-Substitution

                   pOH = 14 - 2.7

-Result

                  pOH = 11.3

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
