The pH of a 0.1 M NH3 solution (Kb=1.8×10−5) is: 11.3.

The pH of a 0.25 M solution of NH4+​ at 25 degrees Celsius is approximately 5.43. This is calculated using the ionization reaction of NH4+​ to produce H3​O+ ions.

Calculate the molarity of the NH3 solution that you have. ... Calculate the mass of NH4Cl necessary to end with 0.2 M in 500 mL. Add the volume necessary of NH3 and the mass necessary of NH4Cl, and fill the rest with water.

Text solution The pH of the 0.02 M ammonia solution which is 5% ionized is 11.

Answer and Explanation: The value of acid dissociation constant is small, so 0.20-x can be written as 0.20. Therefore, the pH of the solution is 4.96.

The equation is pH = pKa + log([NH3]/[NH4+]), We know that the Ka for NH4+ is 5.6 x 10^-10, so, the pKa will be -log(5.6 x 10^-10), which equates to 9.25. Substituting the given concentrations into the equation gives: pH = 9.25 + log (0.25/0.45) which is approximately 8.94. So, the pH of this solution is roughly 8.94.

The pH of 0.2 M solution of ammonia is 10.78.
