Question

what can you say about the PH of a solution that liberate CO2 from sodium carbonate?write the balanced chemical equation for the reaction

Answer 1

The pH of solution which liberate CO2 from Na2CO3 should be less than 7 as acid can do this.The Balanced chemical equation is:
Na2CO3 + 2HCl ----->
2NaCl+ H2O+CO2
As salt and water is formed hence it is neautrilization reaction. I hope this may help you.

Answer 2

Answer:The solution liberates CO2 from sodium carbonate has phone value below 7 and hence it is acidic in nature. Since acids react with carbonates to liberate CO2 as :

Carbonate+dil. acid ------> salt + water + CO2

FOR EXAMPLE :

NaHCO3 + HCL --------> NACL +H2O+ CO2
