# ammonium hydroxide is a weak base because

b) It is completely ionized in aqueous solution. Password must contain at least one uppercase letter, a number and a special character. = Correct Answer .... not really. Molecules of "ammonium hydroxide" don't exist. What professor is this problem relevant for? ", http://en.wikipedia.org/wiki/Ammonium_hydroxide. conducts electricity. You can follow their steps in the video explanation above. Our expert Chemistry tutor, Dasha took 1 minute and 36 seconds to solve this problem. What is the definition of a Base and what is the principals of water? Drag the appropriate items to their repective bins. Ammonia is a weak base because the equilibrium lies far to the left.

According to Brønsted–Lowry concept a weak base may also be defined as a compound with incomplete protonation . which makes you more jittery coffee or tea? That would make it a strong base. By registering, I agree to the Terms of Service and Privacy Policy, Concept: The Classification of Electrolytes, Ammonium hydroxide is a weak base because, a. it is a dilute solutionb. it is a dilute s...as low difficulty. It therefore, can't "dissociate to a slight extent," because there aren't any molecules of NH4OH to dissociate. A weak base is a base that does not ionize fully in an aqueous solution. A solution containing an electrolytea. This is something you need to figure out for yourself or you won't learn anything. it is completely ionized in aqueous solution. The chief was seen coughing and not wearing a mask. Based on our data, we think this problem is relevant for Professor Bennett's class at ECU. Technically, not even (E) is correct. How long does this problem take to solve? What scientific concept do you need to know in order to solve this problem? The entire premise of the question is flawed. Ammonium Hydroxide does not undergo complete ionization: $$NH_4OH\to NH_4^+ +OH^-$$ It presupposes that there are undissociated NH4OH molecules in water, and that simply isn't the case. I went to a Thanksgiving dinner with over 100 guests. In water, there are no NH4OH molecules to be a "weak base." Ammonium hydroxide is a weak base because. NH3(aq) + HOH(l) <==> NH4+ + OH- ............. Kb = 1.8x10^-5. It doesn't. Weak base show a relatively low pH compared to strong base. it dissociate slightly in water compare to a strong base like NaOH that would dissociate 100% Our tutors have indicated that to solve this problem you will need to apply the Electrolytes concept. In water, a substance that ionizes completely in solution is called a:a. electrolyteb. it dissociates only slightly in watere. -- Nope. c) It is a dilute solution. = Correct Answer. b) It is completely ionized in aqueous solution. Or if you need more Electrolytes practice, you can also practice Electrolytes practice problems. is insoluble. Our tutors rated the difficulty ofAmmonium hydroxide is a weak base becausea. Molecules of "ammonium hydroxide" don't exist. There are no molecules of NH4OH to "dissociate. a) It cannot hold on to its hydroxide ions. Still have questions?

If you forgot your password, you can reset it. It is not soluble in water c. it cannot hold on to its hydroxide ions d. it dissociates only slightly in water e. it … e) It dissociates only slightly in water. d) It is only slightly soluble in water. You should be able to figure it out from that. weak electrolytec. What we call "ammonium hydroxide" is actually ammonia, NH3, dissolved in water, in equilibrium with small amounts of NH4+ and OH-. Should I call the police on then? .... nonsense. Does that mean it easily ionizes to make OH-? a. it is a dilute solution b. Which of the following can be characterized as a strong electrolyte. What we call "ammonium hydroxide" is actually ammonia, NH3, dissolved in water, in equilibrium with small amounts of NH4+ and OH-. e) It dissociates only slightly in water. nonelectrolyte. b. does not conduct electricity. Get your answers by asking now. You can view video lessons to learn Electrolytes. it cannot hold on to its hydroxide ionsd. .... Ammonia is indeed slightly soluble in water, but that is not what makes it a weak base. nonconductord. In water, there are no NH4OH molecules to be a "weak base." ... "Strong" or "weak" refer to the degree of ionization, not concentration. It therefore, can't "dissociate to a slight extent," because there aren't any molecules of NH4OH to dissociate.
