Question

write the chemical equation for the reaction involved in the standardization of Hcl solution by std Na2Co3 solution ​

Answer 1

Explanation:

The equation for the first stage of the reaction between sodium carbonate and hydrochloric acid is shown below again: Na2CO3(aq) + HCl(aq) → NaHCO3(aq) + NaCl(aq) From the equation, you can see that 1 mole of Na2CO3 will react with 1 mole of HCl.

Answer 2

Answer:

NaHCl 3(aq) +HCl (aq) >NaCl (aq) + CO2 (g) + H2O (1) From the equation,you can see that 1 mole of NaHCO3 will react with 1 mole of HCl. The number of moles of NaHCO3 is equal to the number of moles of Na2CO3.
