### pH Change Calculation in Buffer Solutions#### Problem Statement**General Chemistry 4th Edition**By McQuarrie, Rock, and GalloglyUniversity Science Books presented by Macmillan LearningCalculate the change in pH when 5.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH₃(aq) and 0.100 M in NH₄Cl(aq). Consult the [table of ionization constants](https://example.com/table) as needed.\[ \Delta \text{pH} = \] Calculate the change in pH when 5.00 mL of 0.100 M NaOH is added to the original buffer solution.\[ \Delta \text{pH} = \] ---This exercise aims to test your understanding of buffer solutions and their capacity to resist changes in pH upon the addition of strong acids or bases. Use the provided concentrations and volumes as well as ionization constants to compute the changes accurately. For reference, the table of ionization constants can help determine the dissociation constants (Ka and Kb) necessary for these calculations. Ensure to carry out the steps methodically, considering the molarity and volume changes upon addition of the acids or bases, and apply the Henderson-Hasselbalch equation or relevant buffer equations as needed. ### pH Calculation Exercise**Question 1:**Calculate the pH of the resulting solution if 28.0 mL of 0.280 M HCl(aq) is added to 38.0 mL of 0.280 M NaOH(aq).\[ \text{pH} = \_\_\_\_\_\_\_\_\_\_ \]**Question 2:**Calculate the pH of the resulting solution if 28.0 mL of 0.280 M HCl(aq) is added to 18.0 mL of 0.380 M NaOH(aq).\[ \text{pH} = \_\_\_\_\_\_\_\_\_\_ \]#### Instructions:1. In the space provided, calculate the pH of each solution after mixing the given volumes and molarities of hydrochloric acid (HCl) and sodium hydroxide (NaOH).2. For each calculation, assume complete dissociation of HCl and NaOH in the solution.3. Consider the neutralization reaction between HCl and NaOH:\[ \text{HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)} \]4. Determine the resulting concentrations of H⁺ and OH⁻ ions after mixing, and apply the formula for pH calculation where necessary.These exercises are designed to help you practice and understand acid-base neutralization reactions and how to calculate the pH of the resultant solutions.
