A metal immersed in acid will gradually dissolve as the chemical reaction consumes it. The sodium flame test gives strong orange color. Let us see facts about HCl +Na.
HCl acid is a strong acid with a pKa value of -7. Sodium is an element with atomic number 11 belonging to the S- block. Its mass number is 22, and it has one valence electron. It is an important element that plays a vital role in the human body.
Let us discuss the type of reaction, balancing the reaction of HCl and Na and its properties in this article.
What is the product of HCl and Na?
Aqueous Sodium chloride and Hydrogen gas are the products of the reaction Na+ HCl.
What type of reaction is HCl + Na?
The reaction between Na+ HCl is a single displacement reaction.
How to balance HCl + Na?
This reaction needs to be balanced as the number of molecules in the reactants and products are unequal. Therefore, so, we have to balance the equation consequently,
HCl + Na → NaCl + H2
- Step 1–First, we should assign coefficients to all molecules in the reaction. We use A, B, C, and D as we have four molecules. The reaction will look like this,
- A HCl + B Na → C NaCl + D H2
- Step 2 – We use the considered coefficients as alphabet reactants and products
- H=A+ 2D, Cl=A+C, and Na=B+C
- Step 3 – Calculate the coefficient values using by Gaussian elimination method.
- A = 2, B =2, C = 2, and D = 1
- So, the balanced equation of the reaction is,
- 2 HCl + 2 Na → 2 NaCl + H2
HCl + Na titration?
HCl + Na titration does not occur in the reaction for these reasons.
- Na is a metal. And metal cannot be used in the titration.
- HCl is a very strong acid and is unsuitable for titration.
HCl + Na net ionic equation?
H+(aq) + Cl− (aq) + Na+(s) →Na+(aq) +Cl−(aq) +H2(g) Is their net ionic equation.
HCl dissociates to H+ and Cl-, and Sodium is Na+.
HCl + Na conjugate pairs?
The Conjugate pair of HCl is Cl– and Na does not have conjugate pair as it is a metal. A match of compounds whose chemical distinction is one proton is conjugate acid-base pair.
HCl and Na intermolecular forces?
HCl has two forces first one is Dipole-Dipole interaction forces, and the second one is dispersion forces.
HCl + Na reaction enthalpy?
The reaction enthalpy of HCl and Na is not established yet.
Is HCl + Na a buffer solution?
HCl is a strong acid, so the buffer is not formed. A buffer arrangement is shaped when the arrangement contains a rise to several conjugate acid-base sets.
Is HCl + Na a complete reaction?
HCl + Na → NaCl + H2. Adding Na metal to Hydrochloric acid is a complete reaction with aqueous Sodium Chloride as a side product and Hydrogen gas being liberated.
Is HCl + Na an exothermic or endothermic reaction?
The reaction of HCl + Na is exothermic as heat is liberated.
Is HCl + Na a redox reaction?
The reaction of HCl + Na is not a redox reaction, as there is no alteration in the oxidation state.
Is HCl + Na a precipitation reaction?
HCl +Na is not a precipitation reaction, as the cations and anions within the reaction don’t combine to create insoluble ionic solids.
Is HCl + Na reversible or irreversible reaction?
The reaction of HCl + Na is an irreversible reaction because its equilibrium constant is enormous.
Is HCl + Na displacement reaction?
Na+ HCl is a single displacement reaction as sodium displaces Hydrogen. The displacement reaction general equation is 2HCl + 2Na → 2NaCl + H2. In the above reaction, Na displaces H2.
In conclusion, when Na is dipped in HCl, H2 gas is liberated. It is an irreversible, exothermic and single displacement reaction.
