15 Facts on HCl + SrCO3: What, How To Balance & FAQs

Strontium Carbonate is a weak base as it has carbonate and easily reacts with acid. Let us see a few facts on HCl+ SrCO₃.

Strontium Carbonate is also known as Strontianite. It has a Rhombic crystal structure. It is colorless and odorless and emits brilliant red color flame in a flame test. Its density is 3.5 g/cm3. HCl is a very strong acid.

Let us discuss the reaction type, the balancing of the reaction, the enthalpy, and the net ionic equation in this article.

What is the product of HCl and SrCO₃?

HCl + SrCO₃ has the following products. Strontium Chloride (SrCl₂), Carbon dioxide, CO₂ and water.

SrCO₃ + 2HCl → SrCl₂ + CO₂ + H₂O.

What type of reaction is HCl + SrCO₃?

HCl + SrCO₃ reaction is an Exothermic reaction.

How to balance HCl + SrCO₃?

HCL + SrCO₃ reaction is not balanced as the number of molecules in the reactants and product are not equal.

• We should first assign coefficients to all molecules present in the reaction. We use U, V, W, X, and Y as we have five molecules. The reaction will look like this,
• U SrCO₃ + V HCl → W SrCl₂ + X CO₂ + Y H₂O. 
• The labeled coefficients can be used as alphabets for reactants and products.
• Sr = U+ W, C=U +X , O=3U +2X +2Y, H=V+2Y.
• We can calculate the coefficient values using by Gaussian elimination method.
• U=1, V=2,W=1,X=1,Y=1
• So, the balanced equivalence of the reaction is,
• SrCO₃ + HCl → SrCl₂ + CO₂ + H₂O. 

HCl+ SrCO₃ titration?

In HCL + SrCO₃ reaction_, titration does not occur as strong acids like HCl cannot be used for titration.

HCl + SrCO₃ net ionic equation?

HCL + SrCO₃ reaction has the following Ionic equation,

Sr²⁺ + CO₃ ^{2 –} + 2H⁺ + 2Cl^– → Sr²⁺ + Cl^– + CO₂ ⁴⁺ + 2H⁺ + O^2-

• Write the balanced chemical equation and represent the states (physical) of reactants and products.
• SrCO3 (s)+ 2HCl (aq) → SrCl2 (s) + CO2 (g) + H2O (aq).
• Salts, acids and bases dissociate into ions, but pure substances and molecules fail to do so. The final equation after dissociation is
• Sr²⁺ + CO₃ ^{2 –} + 2H⁺ + 2Cl^– → Sr²⁺ + Cl^– + CO₂ ⁴⁺ + 2H⁺ + O^2-.
