What information about a chemical solution can be inferred from knowing its pH value?
1 answer:
Answer:
Refer to the response provided below
Explanation:
By determining the pH level of a chemical solution, one can deduce the concentrations of hydrogen or hydroxyl ions within it.
pH indicates the solution's acidity or basicity. It can be mathematically represented as:
pH = where
indicates the concentration of hydrogen ions.
Additionally,
pH = 14 - pOH, where pOH =
A higher results in a lower pH, whereas an increase in the
leads to a higher pH. The pH scale runs from 0 to 14, with a neutral point at 7.

Answer: The correct selection is (b).
Explanation:
The energy required to detach an electron from an atom or ion in its gaseous state is termed ionization energy.
This indicates that a smaller atom necessitates a greater amount of energy to remove its valence electron. The reason for this is that there exists a strong attraction between the nucleus and the electrons in smaller atoms or elements.
Therefore, a significant amount of energy is needed to dislodge the valence electrons.
The electronic configuration for helium is . Hence, due to its fully occupied valence shell, it exhibits greater stability.
Consequently, a large amount of energy is needed to remove an electron from a helium atom.
In conclusion, from the choices provided, the ionization energy of helium will be greater than that of the diatomic molecule.
