Define the term ionization energy. Choose one:
olga nikolaevna [1]

Answer:

A. The amount of energy needed to remove 1 mole of electrons from 1 mole of ground-state atoms or ions in the gas phase.

Explanation:

Ionization energy is the quantity of energy required to remove an electron in ground electronic state from an isolated gaseous atom or ion, resulting in a cation.  kJ/mol is the expresion we use for this energy, it refers to the amount of energy it takes for all the atoms in a mole to lose one electron each.

 Ionization energy can be used as an indicator of reactivity and can be used to help predict the strength of chemical bonds because the more electrons are lost, the more positive the ion will be and the harder it will be to separate the electrons from the atom.

I hope you find this information useful and interesting! Good luck!

Explanation:

This is because the solution only contains water and a salt that is neutral.

Since neither H+ or OH-, molecules remain in the solution.

We can conclude that the equivalence point is 7.0.
