Proton Condition and Electroneutrality

Recommended Posts

Posted (edited)

Hey everyone,

I have a question about a problem related water chemistry. 

0.3 mol K3PO4 + 0.1 mol NaCl dissolve in 1L water.

1-) evaluation of proton y and electroneutrality (using both graphic and electroneutrality method)

2-) Determine all the species formed in the system using the chemicals and concentrations given in the first question. Calculate the concentration of each species.

 For the first one I made that, Is it correct ?

a-) proton condition = electroneutrality = [K+] + [Na+] + [H+] = [H2PO4-] + 2*[HPO42-] + 3*[PO43-] + [OH-] + [Cl-]

If it is, could you please give me some idea about 2.  

thank you.

Can you use a more 'washed out' font ?
Someone might actually be able to read your post.
Wouldn't want that to happen, would you ?
