Assignment:
Q1. 10.00 mL of 0.1000 M NH3 was diluted with distilled water to 40.00 mL. Calculate the pH of the dilute solution. (Kb NH3 = 1.8*10^-5)
Q2. The dilute solution was titrated with 0.0500 M HCl. Write the equation for the reaction between ammonia and hydrochloric acid. Calculate the pH of the solution after adding 4.00 mL of HCl.
Q3. Calculate the total volume of the solution at equivalence point.
Q4. Calculate the pH of the solution at equivalence point.
Q5. Calculate the pH of the solution after adding two additional drops of HCl after reaching the equivalence point (one drop ~ 0.05 mL)
Provide complete and step by step solution for the question and show calculations and use formulas.
