Explanation:
The pH of a solution depends on the concentration of H+ ions in the solution. In acidic solutions, the concentration of H+ ions is higher, while in basic solutions, the concentration of OH- ions is higher.
1. NaOH: NaOH is a strong base, which means it completely dissociates in water to give Na+ ions and OH- ions. The OH- ions react with H+ ions in water to form H2O molecules. Therefore, the concentration of H+ ions in the solution decreases, and the pH of the solution increases.
2. NH4OH: NH4OH is a weak base, which means it partially dissociates in water to give NH4+ ions and OH- ions. The OH- ions react with H+ ions in water to form H2O molecules. Therefore, the concentration of H+ ions in the solution decreases, and the pH of the solution increases. However, NH4+ ions can also react with water to form NH3 and H3O+ ions, which increases the concentration of H+ ions in the solution and decreases the pH of the solution.
3. CH3COOH: CH3COOH is a weak acid, which means it partially dissociates in water to give CH3COO- ions and H+ ions. The H+ ions react with OH- ions in water to form H2O molecules. Therefore, the concentration of H+ ions in the solution decreases, and the pH of the solution increases.
4. HCl: HCl is a strong acid, which means it completely dissociates in water to give H+ ions and Cl- ions. The H+ ions react with OH- ions in water to form H2O molecules. Therefore, the concentration of H+ ions in the solution increases, and the pH of the solution decreases.
Therefore, the correct sequence of their increasing pH is 4, 3, 2, 1.
