**Table of pH Values for Various Solutions** This table provides the pH values of different solutions, including unboiled and boiled water, as well as several common compounds. Use this data for reference in understanding the acidity or basicity of these solutions. | **Solutions** | **pH values** | |---------------------|---------------| | H₂O (unboiled) | 3.5 | | H₂O (boiled) | 7.0 | | NaCl | 7.0 | | NaC₂H₃O₂ | 9.1 | | NH₄Cl | 4.5 | | NaHCO₃ | 9.5 | | Na₃PO₄ | 11.9 | | Na₂CO₃ | 11.0 | **Explanation of pH Values:** - A pH value of 7 is considered neutral. - pH values less than 7 indicate acidity. - pH values greater than 7 indicate basicity (alkalinity). **Detailed Points:** 1. **H₂O (unboiled)** has a pH of 3.5, indicating it is acidic. 2. **H₂O (boiled)** has a neutral pH of 7.0. 3. **NaCl (Sodium Chloride)** solution has a neutral pH of 7.0, the same as boiled water. 4. **NaC₂H₃O₂ (Sodium Acetate)** has a basic pH of 9.1. 5. **NH₄Cl (Ammonium Chloride)** is slightly acidic with a pH of 4.5. 6. **NaHCO₃ (Sodium Bicarbonate)** shows basicity with a pH of 9.5. 7. **Na₃PO₄ (Sodium Phosphate)** is highly basic with a pH of 11.9. 8. **Na₂CO₃ (Sodium Carbonate)** also shows high basicity with a pH of 11.0. This data is crucial for educators and students to understand the pH levels and the nature (acidic or basic) of various common solutions.
