# Problem: a. NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.030M in NH4Cl at 25°C?b. HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.045 M in NaClO at 25°C?

🤓 Based on our data, we think this question is relevant for Professor Rathbone's class at BLINN.

###### Problem Details

a. NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.030M in NH4Cl at 25°C?

b. HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.045 M in NaClO at 25°C?
