Determine if each solution is acidic, basic, or neutral.

[H3O+] = 1 x 10-10 M; [OH-] = 1 x 10-4 M

[H3O+] = 1 x 10-7 M; [OH-] = 1 x 10-7 M

[H3O+] = 1 x 10-1 M; [OH-] = 1 x 10-13 M

[H3O+] = 1 x 10-13 M; [OH-] = 1 x 10-1 M

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

where are the choice options?

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
