Na3PO4
the valency of element sodium chloride is 1
Na+ valency is one
The correct answer is sodium monohydrogen phosphate.

NaH2PO4(aq) --> Na+(aq) + H2PO4(aq)sodium dihydrogen phosphate --> sodium ion + dihydrogen phosphate ionExplanationDissociation is the breakdown of soluble salts into their respective ions. Sodium dihydrogen phosphate is made up of two ions - sodium and dihydrogen phosphate. Therefore the dissociation of sodium dihydrogen phosphate will produce sodium and dihydrogen phosphate ions.
By considering the valency of sulfate over phosphate, sulfate can be distinguished from phosphate. Sulfate has a valency of 2 where phosphate has 3.
The valency of sodium is +1
The phosphate ion is PO43-
PO4 has its valency 3 but, PO3 also has its valency 3
On its own, the valency of phosphate is 3
the valency of element sodium chloride is 1
Sodium phosphide
The compound with formula Na3PO4 is named "sodium phosphate", "trisodium phosphate", "sodium ortho-phosphate", or "trisodium ortho-phosphate".
Na+ valency is one
sodium acetate and zinc phosphate
The correct answer is sodium monohydrogen phosphate.
Sodium phosphate is a generic term for the salts of sodium hydroxide and phosphoric acid (soluble in water). They are:sodium dihydrogen phosphate, commonly termed monosodium phosphate, (NaH2PO4), is also known as "sodium phosphate, monobasic".disodium hydrogen phosphate, commonly termed disodium phosphate, (Na2HPO4) is also known as "sodium phosphate, dibasic".Trisodium phosphate, commonly shortened to just sodium phosphate, (Na3PO4), is also known as "sodium phosphate, tribasic".sodium aluminium phosphate, (Na8Al2(OH)2(PO4)4).
