What is the hydrogen ion and hydroxide ion concentration for a poh of 3.557? is the solution an acid or a base?

is the hydrogen ion concentration.

0.0002773 M is the hydroxide ion concentration.

The solution has pH value more than 7 which means that it is base.

Explanation:

The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution. Lower the value of pH more acidic will the solution.

Mathematically written as:

The pOH of the solution is defined as negative logarithm of hydroxide ions concentration in a solution. Lower the value of pOH more alkaline will the solution.

Mathematically written as:

The sum of ph and pOH is equal to 14.

pH + pOH = 14

We have:

Solution with pOH = 3.557

The pH of the solution = 14 - pOH = 10.443

is the hydrogen ion concentration.

0.0002773 M is the hydroxide ion concentration.

The solution has pH value more than 7 which means that it is base.

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.
