**Question 2: Comparative Concentrations of H⁺ Ions in Aqueous Solutions**This exercise requires students to arrange the given aqueous solutions based on the concentration of hydrogen ions (H⁺) they contain, from the highest to the lowest. Understanding the nature of each solution is key to answering this question correctly.**Solutions Provided:**a) **0.10 M HNO₃ (Nitric Acid)** - HNO₃ is a strong acid, meaning it fully dissociates in water to produce H⁺ ions. Thus, the concentration of H⁺ ions in this solution is approximately equal to its molarity, 0.10 M.b) **0.10 M H₂CO₃ (Carbonic Acid)** - H₂CO₃ is a weak acid and only partially dissociates in water. Therefore, the concentration of H⁺ ions will be less than 0.10 M and dependent on its dissociation constant.c) **0.10 M NaOH (Sodium Hydroxide)** - NaOH is a strong base and dissociates completely in water to produce OH⁻ ions. It neutralizes H⁺ ions, effectively decreasing the overall concentration of H⁺ ions in the solution.**Ordering:**1. **0.10 M HNO₃** - Highest concentration of H⁺ ions due to complete dissociation.2. **0.10 M H₂CO₃** - Lower concentration of H⁺ ions due to partial dissociation.3. **0.10 M NaOH** - Lowest concentration of H⁺ ions, as it is a strong base that neutralizes H⁺ ions.By understanding the properties of these substances, students can effectively determine the relative concentration of H⁺ ions in each solution.

Acid is a species that gives H+ ion in aqueous solution. So, higher the acidity, higher will be the H+ ion concentration. Here, all the solutions have same concentration. But, we know that H NO 3 is a strong acid, so it completely dissociate into H+ ion. Whereas H2 CO 3 is a weak acid, so it cannot completely dissociate. And Na OH is a strong base. We can see the dissociation as below : Thus, H NO 3, being strongest acid, have highest H+ ion concentration. The order is : H NO 3 > H2 CO 3 > Na OH
