Achemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. he has a 0.1922 m standard sodium hydroxide solution. he takes a 25.00 ml sample of the original acid solution and dilutes it to 250.0 ml. then, he takes a 10.00 ml sample of the dilute acid solution and titrates it with the standard solution. the endpoint was reached after the addition of 13.68 ml of the standard solution. what is the concentration of the original sulfuric acid solution?

Explanation:

The given data is as follows.

          Concentration of standard NaOH solution = 0.1922 M

Let the original acid solution concentration be x.

                                     = 0.1 x M

= 10.00 mL (given)

The reaction equation is as follows.

   Concentration × Volume of = Concentration × Volume of NaOH

                  x = 1.314 M

Therefore, we can conclude that the concentration of the original sulfuric acid solution is 1.314 M.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
