The compound sodium carbonate is a strong electrolyte because it completely dissociates when placed in water into its component ions. The equation of the reaction can be expressed as:
The dissociation leads to the formation of sodium and carbonate ions with the latter held together by its internal covalent bond.
This is unlike weak electrolytes that do not dissociate completely in water or aqueous solutions. Only a small fraction of the solute exists as ions in the solution.

Answer:
1. C = 0.73 M.
2. pH = 0.14
Explanation:
The reaction is the following:
HCl + NH₃ ⇄ NH₄⁺Cl⁻
From the titration, we can find the number of moles of HCl that were neutralized by the ammonia.
Where "a" is for acid and "b" is for base.
The number of moles is:
Where "C" is for concentration and "V" for volume.
Hence the initial concentration of the acid is 0.73 M.
The original pH of the acid is given by:
Therefore, the original pH of the acid is 0.14.
I hope it helps you!
