In the titration of a solution of weak monoprotic acid with a 0.1525 M solution of NaOH, the pH half way to the equivalence point was 4.48 . In the titration of a second solution of the same acid, exactly twice as much of a 0.1525 M solution of NaOH was needed to reach the equivalence point. What was the pH half way to the equivalence point in this titration

Pauling and lewis questioned the extreme definitions of bonds. they wondered if bonds might be described somewhere in between the two extremes (covalent and ionic). on the basis of experimental data,pauling confirmed that bonds could be ionic, covalent, and for those, in between, exhibit a degree of ionic character. he theorized that the major factor was how strongly the atoms in the bond attracted the electrons. pauling called this factor - the tendency of an atom to attract electrons in a bond.

Based on its chemical properties, identify the position of each chemical family on the periodic table.
