Question

Can you please answer 15.54 and show all of the steps to the solution 

**15.53** Does the pH increase, decrease, or remain the same on the addition of each of the following: (a) NH₄NO₃ to an NH₃ solution (b) Na₂CO₃ to an NaHCO₃ solution (c) NaClO₄ to an NaOH solution **15.54** Calculate the pH of a solution that is 0.10 M in NaF. **15.55** Calculate the pH of a solution prepared by mixing equal volumes of 0.20 M methylamine (CH₃NH₂, K_b = 3.7 × 10⁻⁴) and 0.60 M CH₃NH₃Cl. **Diagram Description:** The diagram shows a molecular structure. It is a ball-and-stick model representing the molecules involved. - The central atom is connected to three hydrogen atoms and one additional atom which appears to represent nitrogen, following the typical structure of methylamine. - Typically, the black ball represents carbon (C), the blue ball represents nitrogen (N), and the white balls represent hydrogen (H).
