**Pre-lab question #5: On the basis of Le Chatelier's Principle. Explain why Ag₂CO₃ dissolves when HNO₃ is added.**1. \( \text{2 Ag}^+ (\text{aq}) + \text{CO}_3^{2-} (\text{aq}) \leftrightarrow \text{Ag}_2\text{CO}_3 (\text{s}) \)2. \( \text{2 H}^+ (\text{aq}) + \text{CO}_3^{2-} (\text{aq}) \leftrightarrow \text{H}_2\text{CO}_3 (\text{aq}) \rightarrow \text{CO}_2 (\text{g}) + \text{H}_2\text{O} (\text{l}) \)When HNO₃ is added:- \( \text{HNO}_3 \uparrow \rightarrow \text{H}^+ \uparrow \) → equilibrium (2) shifts right → \( \text{CO}_3^{2-} \downarrow \)- \( \text{CO}_3^{2-} \downarrow \) → equilibrium (1) shifts left → \( \text{Ag}_2\text{CO}_3 \) dissolves**True** **False****Explanation of Diagram:**The image contains two chemical equilibrium equations. The first equation depicts the equilibrium between silver ions (\( \text{Ag}^+ \)), carbonate ions (\( \text{CO}_3^{2-} \)), and solid silver carbonate (\( \text{Ag}_2\text{CO}_3 \)). The second equation represents the reaction between hydrogen ions (\( \text{H}^+ \)) and carbonate ions (\( \text{CO}_3^{2-} \)), forming carbonic acid (\( \text{H}_2\text{CO}_3 \)), which decomposes into carbon dioxide gas (\( \text{CO}_2 \)) and water (\( \text{H}_2\text{O} \)). The explanation uses Le Chatelier's Principle to describe that the addition of HNO₃ increases hydrogen ion concentration. This causes the second equilibrium to shift to the right, reducing the concentration of carbonate ions and leading to the dissolution of \( \text{Ag}_

When HNO3 is added to the solution, Ag2CO3 get dissolved.
