Write the acid and base used to make Na2CO3 salt

Answer» HEY mate here is your answer》》

When sodium carbonate dissolves in water it DISSOCIATES into two sodium (Na+) ions and a carbonate (CO3–2) ion;-

Na2CO3 (s) —-> 2 Na+(aq) + CO3–2(aq)

The carbonate ion is able to remove protons (H+) from water to form bicarbonate ions and hydroxide ions. HENCE it is the conjugate base of the bicarbonate ion;

CO3–2(aq) + H2O(l) ←-> HCO3-(aq) + OH-(aq)

The overall increase in OH- ions due to these reactions results in an increase in the pH of the solution, and cause it to BECOME alkaline.
