15 Facts on HCl + Na2PO4: What, How To Balance & FAQs

Hydrochloric acid is a strong acid. In contrast, sodium phosphate is a salt with a strong base, i.e., sodium hydroxide. Let us study how HCl and Na2PO4 reageer.

HCl+ Na2PO4 react to give salt metathesis reaction. HCl is an aqueous solution of hydrogen chloride. It dissociates readily to give proton and chloride anions. In contrast, sodium phosphate is a dibasic compound. It is an inexpensive, non-toxic compound commonly used for baked goods.

In this article, we will study the type, product, and balancing of the HCl + Na2PO4 reaksie.

What is the product of HCl and Na2PO4?

HCl en Na2PO4 react to form sodium chloride and dihydrogen phosphate.

Na2PO4 + 2HCl → 2NaCl + H2PO4

What type of Reaction is HCl + Na2PO4

The HCl + Na2PO4 is 'n dubbele verplasingsreaksie as the cation and anion of the two ionic compounds exchange bonds to create 2 new compounds with nearby or equivalent bonding affiliations.

How to Balance HCl + Na2PO4

The equations is balanced by a hit-and-trial method as follows. 

  • To balance HCl + Na2PO4 equation, we will balance the number of sodium atoms both in reactant and product side.
  • Na2PO4 + HCl → 2NaCl + H2PO4
  • Now, we will balance the number of chlorine atoms.
  • Na2PO4 + 2HCl → 2NaCl + H2PO4
  • Next, we will balance the oxygen and hydrogen atoms as we can see that the number of hydrogen and oxygen is already balanced.
  • Thus, we can conclude that the above equation is a required balance equation.
  • Na2PO4 + 2HCl → 2NaCl + H2PO4

HCl + Na2PO4 titrasie

HCl + Na2PO4 does not undergo titrasie as no equivalence point is observed during the reaction.

HCl + Na2PO4 Netto Ioniese Vergelyking

  • To calculate the net ionic equation of HCl + Na2PO4, the balanced equation is written first.
  • Na2PO4 + 2HCl → 2NaCl + H2PO4
  • The total ionic equation for the balanced equation is as follows:
  • 2 Na+ + PO4-3 + 2 uur+ + 2Cl- → 2Na+ + 2Cl- + H2PO4
  • Hence, the net equation is:
  • PO4-3 + 2 uur+ → H2PO4

HCl + Na2PO4 Vervoegde pare

  • The conjugate pair of hydrochloric acid is Cl-.
  • There is no conjugate pair of Na2PO4 because of the absence of protons in sodium phosphate.

HCl and Na2PO4 Intermolekulêre magte

  • Dipole-dipole intermolekulêre krag is present between the molecule of hydrochloric acid.
  • There is an electrostatic force of attraction between molecules of sodium phosphate.

HCl + Na2PO4 Reaksie Entalpie
