Question

Help please. Not understanding how the atoms are broken down to the ions. I keep getting the wrong balanced equation.

Consider the reaction when aqueous solutions of sodium phosphate and zinc sulfate are combined. The net ionic equation for this reaction is:

Answer 1

NaH2PO4^ (aq) + ZnSO4 (aq) ===> Na2SO4(aq) + ZnPO4 + H2(g)

Answer 2

NaH2PO^4 - why does it require a H2?

Answer 3

2 - now just write them again but as separated ions.

Na+ (a) + PO4-(aq) + Zn^2+(aq) + SO4(aq) ===> 2Na(aq) + SO4(aq) + Zn(aq) + PO4(aq) + H2(g)

3- cut out the spectator ions and remember don't break down gases, liquids or solids, only aqueous solutions

Answer 4

Thank you very much! Why is the H2 required though? I've never seen that

Answer 5

NaH2PO^4 its called Sodium dihydrogen phosphate :) this type of compounds does exist :)
its not H2 gas but two hydrogen atoms in that compounds :)

Answer 6

I'm sorry the formula for sodium phosphate is NA3PO4

Answer 7

well done miss @RANE and Mr @chmvijay :)

Answer 8

Hm, how are you suppose to know to write that if all it says is sodium phosphate? or is that something to just memorize? that's really confusing

Answer 9

so
NaH2PO4^ (aq) + ZnSO4 (aq) ===> Na2SO4(aq) + ZnPO4 + H2(g)

Answer 10

yup u should change it to Na3PO4

Answer 11

good girls so rane u are help line service now

Answer 12

thankx @rina

Answer 13

remember wht was i and wht are u now..

Answer 14

no! I'm just answering q's, tum to….

Answer 15

I still don't understand where that H2 comes from :(

Answer 16

sis rane i will mention u who ever needs help in chem ok

Answer 17

Is it required in the formula ?

Answer 18

and change what to Na3PO4?
