22 Which of the following statements about acids and alkalis is TRUE?
(1 Point)
ammonium hydroxide is alkaline due to the presence of OH+ ions
hydroxide ions make sodium hydroxide solution alkaline
O hydrochloric acid solution is acidic because it contains hydride ions

''hydroxide ions make sodium hydroxide solution alkaline'' is true.

Explanation:

In the first sentence, OH+ ions is incorrect. It has to be OH- ions.

In the last sentence, hydride ions(H-ions) is incorrect. It has to be hydrogen ions(H+ ions).

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
