simply use the formula DeltaTf=iKfm i= van't hoff number; Na3PO4 (sodium phosphate) van't hoff number is 4 m= molality moles of solute/kg of solvent in this case H2O Kf= the given number for Na3PO4 (sodium phosphate) is is ???*C/m just multiply those three things and that gives you the freezing point depression so we take the normal freezing point of water 0*C and we subtract the number we just calculated and that will give us the freezing point

What is the compound formules for sodium 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).
What is the freezing point of sodium in Celsius?
Sodium metal freezes at 97.72 oC

What is the melting point for sodium?
97.72 degress
Zinc acetate react with sodium phosphate?
sodium acetate and zinc phosphate
What is the chemical name for Na2HPO4?

What is the dissociation equation for sodium dihydrogen 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.
What is the chemical formula for sodium and phosphate?
sodium is Na phosphate is PO43- again, if you meant to ask the formula of the compound sodium phosphate it is Na3PO4
What is the formula for sodium phosphate tribasic?
The formula for sodium phosphate tribasic is Na3PO4
What is Na2HPO4.7H2O?
Sodium Monohydrogen Phosphate heptahydrate, Sodium phosphate dibasic heptahydrate
