What is the pH of HC2H3O2?
Acetic acid is a weak monoprotic acid. In aqueous solution, it has a pKa value of 4.76. Its conjugate base is acetate (CH3COO−). A 1.0 M solution (about the concentration of domestic vinegar) has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated.
What is the kb of NH4Cl?
1.8 x10-5
Example : Calculate PH and Kh of 0.1 M ammonium chloride NH4Cl). (Kb = 1.8 x10-5 at room temperature).
How do you find KB from Ka?
Solve the equation for Kb by dividing the Kw by the Ka. You then obtain the equation Kb = Kw / Ka. Put the values from the problem into the equation. For example, for the chloride ion, Kb = 1.0 x 10^-14 / 1.0 x 10^6.

What pH is nh4cl?
While the question is too generic because it does not mention the values, we can say in general that the pH of Ammonium Chloride (NH4Cl) is less than 7. When it is dissolved in water, ammonium chloride breaks down into different ions which are NH4+ and Cl–.
What is the kb of NH3?
