If you have a glass of pure water, without any acids or bases, how many hydronium ions (H[tex]\(_3\)[/tex]O[tex]\(^+\)[/tex]) do you expect?

A. Half the water is hydronium ions
B. As many as there are water molecules
C. None
D. The same number as OH[tex]\(^-\)[/tex]



Answer :

Final answer:

Pure water has a very low concentration of hydronium ions, resulting in neutrality and essentially having no hydronium ions present.


Explanation:

In pure water, the concentration of hydronium ions is very low, with only about 1 in 10 million water molecules naturally breaking down to form a hydronium ion, resulting in a neutral pH of 7.

The self-ionization of water yields an equal number of hydrogen (H+) ions and hydroxide (OH-) ions. This means that hydronium ions (H3O+) are immediately formed in conjunction with hydrogen ions.

Therefore, the correct answer to the question posed is option c) None as the number of hydronium ions in pure water without any acids or bases is extremely minimal.
