Calculate the pH of a solution prepared by adding 45.0 mL of a 0.213 M HCl solution to 125.0 mL of a 0.150 M solution of ammonia. The \(pK_b\) of ammonia is 4.75 at 25°C. Answer. 9.23 (Note that since the ammonia is approximately half-neutralized at this point, this pH is very close to the \(pK_a\) of ammonium, 9.25!)

If 0-561 g of KOH is dissolved in water to give 200 mL of solution at 298 K. Calculate the concentrations of potassium, hydrogen and hydroxyl ions. What is its pH? – To find the concentration of a solution, we need to use the molarity (M) equation. molarity = mass/volume So, to find the concentration of 0.150 M KOH, we would use the following equation: concentration = (0.150 M)*(1 mole/L) Now that we have the concentration, we can use the pH equation to find the pH.
