Hydrogen Ions vs. Hydroxide Ions

[Buffy31]

Hey

I need to know the differences between Hydrogen Ions & Hydroxide Ions...I know a lot (I think) about Hydroxide Ions, but ahve yet to find much on Hydrogen Ions??

Hydroxide ions: produced when water molecules H2O ionize to become hydronium & hydroxide ions

water molecules that carry NEG charge, because they LOST a pos. charged hydrogen ion

is a base ?

pH of 7 or lower

SO..is that all correct??? and if so, hydrogen ions must be an acid?? examples?

thanks

Thanks! I will!

a hydrogen ion is a hydrogen atom with no electrons thus making it a positive charge. the more hydrogen ions in a solution, the more acidic it is. any solution with a ph of 7 or higher, is a base. anything with a ph of 7 or lower is an acid.

i'm not sure if i answered your question but, i had a chemistry major for an anatomy and physiology professor. needless to say we spent a lot of time in chapter 2 than we really needed to!

good luck!!:heartbeat:heartbeat

water actually breaks down to form hydroxide and hydrogen ions:

H2O -> OH- + H+

some texts prefer to use the hydronium ion instead of the hydrogen ion as the product. It's basically talking about the same thing because:

H2O + H+ -> H3O+

Hydronium (H3O+) is formed from the bonding of a hydrogen ion (H+) and a water molecule (H2O).

When talking about acidity you're measuring the concentration of hydrogen ions (H+) or hydronium ions (H3O+). In reality the hydrogen ions are constantly bonded to water and forming hydronium ions as well as the reverse (breakdown of hydronium to form water and hydrogen ions).

It really depends on what text you're reading or what your professor prefers.

hyrdoxide: OH- negatively charged ion. basic.

hyrogen ion/hydronium ion: H+/H30+ positively charged ion. acidic.
