### pH Values of Various SolutionsThe table below lists various solutions and their respective pH values. The pH scale measures how acidic or basic a solution is, with values below 7 indicating acidity, values of 7 being neutral, and values above 7 indicating alkalinity.| **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 Solutions and Their pH Levels1. **H₂O (unboiled)** - pH 3.5: Unboiled water exhibits a slightly acidic nature, possibly due to dissolved carbon dioxide from the air forming carbonic acid. 2. **H₂O (boiled)** - pH 7.0: Boiled water is neutral, as boiling removes dissolved gases like CO₂, which can affect the pH.3. **NaCl** - pH 7.0: Sodium chloride (table salt) in water has a neutral pH, indicating no acidic or basic properties.4. **NaC₂H₃O₂** - pH 9.1: Sodium acetate, often used in hand warmers and as a food preservative, shows a basic pH level.5. **NH₄Cl** - pH 4.5: Ammonium chloride, used in fertilizers and cough medicine, has an acidic pH.6. **NaHCO₃** - pH 9.5: Sodium bicarbonate (baking soda), commonly used in baking and cleaning, has a basic pH.7. **Na₃PO₄** - pH 11.9: Sodium phosphate, used in detergents and water treatment, is strongly basic.8. **Na₂CO₃** - pH 11.0: Sodium carbonate (soda ash), used in glass making and as **Lab Report #5-2-2:****0.1 M NaHCO₃ solution, using the given pH data, write net-ionic equation for hydrolysis:**1. \( \text{NaHCO}_3 + \text{H}_2\text{O} \leftrightarrow \text{Na}^+ + \text{H}_2\text{CO}_3 + \text{OH}^- \)2. \( \text{CO}_3^{2-} + \text{H}_2\text{O} \leftrightarrow \text{HCO}_3^- + \text{OH}^- \)3. \( \text{HCO}_3^- + \text{H}_2\text{O} \leftrightarrow \text{H}_2\text{CO}_3 + \text{OH}^- \)(Students are likely expected to analyze the given pH data and select the correct net-ionic equation for the hydrolysis of the bicarbonate ion \( \text{HCO}_3^- \) in the solution).
