albertlee Posted October 29, 2004 Posted October 29, 2004 Would any molecule with partial charge ever bonded with any ion with a complete charge?
albertlee Posted October 29, 2004 Author Posted October 29, 2004 Well, I think so.., as an example from one of my thread, NH3, an amonia molecule, has 3 hydrogen pulling the Nitrogen atom, which Nitrogen is the lone pair... and if it is near a hydrogen ion, it shall be attracted to it... hence forming a NH4 ion... but on the other hand, how come the lone pair of water cant make an ion out of this way?
Jake712 Posted October 29, 2004 Posted October 29, 2004 Actually Albert, it does. Water is constantly forming H+ (hydronium ions) and OH- (hydroxide) ions by combinding to make H3O and OH. However, these two cancel each other out giving water its ph of 7. Acidic and Basic substances have an imbalance in its hydronium and hydroxide ion equalibrium. Plus, the number of atoms that do combinde is so small and happens so quickly that we cannot see it.
albertlee Posted October 29, 2004 Author Posted October 29, 2004 umm... but that's between two water molecules!!

Gilded Posted October 29, 2004 Posted October 29, 2004 He probably meant that the H2O attracts the H+, which "combines" the two to make H3O+. And then, when H3O+ meets his long lost love OH-, two water molecules are born. Need... sleep... chemistry at about 1:20 AM... not good.
serunato Posted October 29, 2004 Posted October 29, 2004 Would any molecule with partial charge ever bonded with any ion with a complete charge? Yes, coordintation complexes. Neutral ligands form bonds with metal cations and those bonds often have covalent character, mostly for the d-block metals only. Like [Fe(H20)6]3+.
Primarygun Posted October 30, 2004 Posted October 30, 2004 Acid dissolves in water to give a H+ and anion. Then H3O+ is formed to give a change in pH.

Need... sleep... chemistry at about 1:20 AM... not good.[/quote'] Is H3O an ion???? name me a compound form with this ion... Secondly, how water molecules do not combine in this way, as far as I know, the water molecules have a partial positive charge on Oxygen atom, and partial negative charge on Hydrogen atoms.... so, the partial charge attracts to the oposite partial charge of another water molecule... ALbert
Primarygun Posted October 30, 2004 Posted October 30, 2004 Is H3O an ion???? name me a compound form with this ion... Hydronium ion H3O+ is an ion. But I don't know whether H3O is in reality or not. Like there is no sulpur oxide but has sulphur dioxide. the water molecules have a partial positive charge on Oxygen atom, and partial negative charge on Hydrogen atoms Not oxygen has a partial positive but a partial negative. Hydrogen atom has a partial positive charge. IT is that the water molecule do. One WatER molecule attract the other one as they are polar molecule , so the attraction is not small ( but not very large). So hydronium ion and hydroxide ion form but the composition is not very high. There is a water decompose constant. http://www.wordiq.com/definition/Dissociation_constant I haven't learnt the acid-base reaction, now learning the displacement reaction, so I can't tell you what the product it after it combine with something, like metal...
Skye Posted October 30, 2004 Posted October 30, 2004 Normally excess H+ ions in solution bind to water molecules to form H3O+, and this what participates in reactions. People write H+ instead because it's simpler.
albertlee Posted October 30, 2004 Author Posted October 30, 2004 What situation H3O+ is formed? secondly, again, is there any compound having this ion?
albertlee Posted October 30, 2004 Author Posted October 30, 2004 Any body can help on my previous message???
Primarygun Posted October 31, 2004 Posted October 31, 2004 "Hydronium is the cation that forms from water in the presence of hydrogen ions. These hydrons do not exist in a free state: they are extremely reactive and are solvated by water. An acid is generally the source of these hydrons; however, since water can behave as an acid, hydronium exists even in pure water. This special case of water reacting with water to produce hydronium (and hydroxide) ions is commonly known as the self-ionization of water. The resulting hydronium ions are few and short-lived."
Primarygun Posted October 31, 2004 Posted October 31, 2004 By the way, anyone know what's pOK or maybe pKO stands for?
albertlee Posted October 31, 2004 Author Posted October 31, 2004 Any way, I think I should stop here... because things are getting out of control for me to understand!!
