AI Thread Summary
Sodium monohydrogen phosphate has the chemical formula Na2HPO4. The bonding in this compound involves one hydrogen atom bonded to an oxygen atom in the phosphate group, while two sodium cations form ionic bonds with two other oxygen atoms in the phosphate. The phosphate ion carries a -3 charge, and the hydrogen can either accept or donate an electron, facilitating the bonding with sodium, which typically loses one electron. Understanding these interactions clarifies how the formula is derived and the nature of the compound's bonding.

[SOLVED] Sodium monohydrogen phosphate

In a question, I came across the compound sodium monohydrogen phosphate. It only gave the name and so I needed to work out the formula.

The real forumla is Na2 H (PO4). I am wonderin about the bonding of this molecule. Phosphate has a -3 charge. H could accept or give away an electron right? And the sodiums are metals, which want to give away an electron each.

How do they bond together? How could I work out that forumla knowing this?


Cheers folk, I am not an expert on chemistry! :)
 
Chemistry news on Phys.org
There is one hydrogen bond to an oxygen of phosphate and two ionic bonds to sodium cation with two other oxygens of phosphate.
 
Ah yea I see it now, very simple. Thanks.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
