, ammonia is considered as a base. Normally, it is accepted that a strong acid give rise to a weak conjugate base and a weak base give rise to a strong conjugate acid. As ammonia can give rise to ammonium ion, which is a strong conjugate acid; ammonia is classified as a weak base....

On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. Conjugate acid is an acid that formed when the parent base compound gains one proton and the conjugate base is a base that formed when the parent acid compound loses one proton. Is NO2 a weak conjugate base? Expert...
Answer to: NH_3 is a weak base (K_b = 1.8 x 10^-5) and so the salt NH_4Cl acts as a weak acid. What is the pH of a solution that is 0.015 M in...
Explanation: And since ammonia does NOT contain hydroxide ions, i.e. its chemical formula is NH3 , it does not fall under the Arrhenius' umbrella. We classify ammonia as a Bronsted-Lowry base...and its conjugate acid is ammonium ion, NH+4 ...Similar...
