Below are the steps that should be followed lớn get the balanced equation

• The number of Ba, C, and O atoms on left hand side and right hand side is same.
• HCl + BaCO3 = BaCl2 + CO2 + H2O
• The number of H and Cl atoms, on left hand side and right hand side is 1 and 2 respectively.
• HCl  +  BaCO3  = BaCl2 + CO2 + H2O
• We will multiply HCl with 2 ví that number of H and Cl atoms becomes same.
• Finally, the balanced equation is as follows.
• 2HCl + BaCO3 = BaCl2 + CO2 + H2O

## HCl + BaCO3 titration

To determine the amount of the poorly insoluble salt BaCO3 by HCl, we have lớn bởi back titration.

Pipette, volumetric flask, conical flask, measuring cylinder, burette, and titration stand

### Indicator

Phenolphthalein is used as indicator in this titration procedure.

### Procedure

• Take BaCO3 sample in a conical flask and HCl (known volume and concentration) was added using a pipette.
• Mix it properly and add a few drops of indicator.
• Titrate the excess HCl with NaOH solution of known concentration from a burette till the color changes lớn light pink.
• Repeat the procedure 2-3 times lớn avoid errors and note down the burette reading.
• Finally, using the formula S1V1 = S2V2, the amount of unreacted HCl can be found.
• From the amount of HCl reacted with BaCO3, the amount of BaCO3 can be determined.

## HCl + BaCO3 net ionic equation

The net ionic equation for the reaction HCl + BaCO3 is

CO32− (aq) + 2H+ (aq) → H2O (l) + CO2 (g)

To derive the net ionic equation, follow the below steps.

• Soluble ionic compounds can dissociate into cations and anions.
• HCl, BaCO3, and BaCl2 being ionic, can be written as cations and anions.
• 2H+ (aq) + 2Cl (aq) + Ba2+ (aq) + CO32− (aq) = Ba2+ (aq) + 2Cl (aq) + H2O (l) + CO2 (g)
• Finally, after canceling the spectator ions from both sides, we can get the net ionic equation.

## HCl + BaCO3 reaction enthalpy

The reaction enthalpy value for the reaction HCl + BaCO3 is -2.0 kJ/mole. It is calculated as follows.

Change in Enthalpy = (enthalpies of formation of all products) – (enthalpies of formation of all reactants)

= [(-871.9) + (-285.8) + (-393.5)] – [2*(-167.2) + (-1214.8)]

= -2.0 KJ/mol.

## Is HCl + BaCO3 a buffer solution

HCl + BaCO3 cannot produce a buffer solution because HCl is a strong acid, and BaCO3 does not contain the conjugate base of HCl.

HCl + BaCO3 cannot be called a redox reaction because the oxidation states of the atoms of the reactant and product molecules are unchanged.

## Is HCl + BaCO3 a precipitation reaction

HCl + BaCO3 is not a precipitation reaction because the product BaClis a water-soluble solid, CO2 is a gas, and H2O is liquid.

## Is HCl + BaCO3 reversible or irreversible reaction

HCl + BaCO3 is an irreversible reaction as the reaction does not proceed back lớn the left-hand side once the products are formed.

## Is HCl + BaCO3 displacement reaction

HCl + BaCO3 is a displacement reaction as ions are swapped between two reactants BaCO3 and HCl.

#### Conclusion
