WebDec 1, 2014 · NH3 is ammonia, and the Kb for ammonia is 1.8 times 10 to the negative 5. Aniline is C6H5NH2. Notice it has a lower value for the Kb, 4.3 times 10 to the negative 10 is a much smaller number, a much smaller value than 1.8 times 10 to the negative 5. Ammonia … WebThe equilibrium constant for the ionization of a base is known as the base ionization constant (Kb). The Kb equation for ammonia is: Kb = [NH+₄] [OH−] / [NH₃] FEW COMMON USES OF STRONG BASES: Strong bases have a slick, soapy texture and a high pH value. Cleaning solutions and antacids both include strong bases. global knowledge egypt address
