What scientific concept do you need to know in order to solve this problem? It therefore, can't "dissociate to a slight extent," because there aren't any molecules of NH4OH to dissociate. It is not soluble in water c. it cannot hold on to its hydroxide ions d. it dissociates only slightly in water e. it … What is the definition of a Base and what is the principals of water? Ammonium Hydroxide does not undergo complete ionization: $$NH_4OH\to NH_4^+ +OH^-$$ Ammonium hydroxide is a weak base because. Join thousands of students and gain free access to 46 hours of Chemistry videos that follow the topics your textbook covers. That would make it a strong base. -- Nope. Based on our data, we think this problem is relevant for Professor Bennett's class at ECU. b) It is completely ionized in aqueous solution. Classify these compounds as soluble or insoluble. which makes you more jittery coffee or tea? Our tutors rated the difficulty ofAmmonium hydroxide is a weak base becausea. According to Brønsted–Lowry concept a weak base may also be defined as a compound with incomplete protonation . The entire premise of the question is flawed. is insoluble. .... nonsense. Our expert Chemistry tutor, Dasha took 1 minute and 36 seconds to solve this problem. b) It is completely ionized in aqueous solution. Which of the following can be characterized as a strong electrolyte. nonconductord. conducts electricity. Get a better grade with hundreds of hours of expert tutoring videos for your textbook. In water, a substance that ionizes completely in solution is called a:a. electrolyteb. You can view video lessons to learn Electrolytes. You can follow their steps in the video explanation above.

What we call "ammonium hydroxide" is actually ammonia, NH3, dissolved in water, in equilibrium with small amounts of NH4+ and OH-. A weak base is a base that does not ionize fully in an aqueous solution. Ammonia is a weak base because the equilibrium lies far to the left. a) It cannot hold on to its hydroxide ions. The chief was seen coughing and not wearing a mask. What we call "ammonium hydroxide" is actually ammonia, NH3, dissolved in water, in equilibrium with small amounts of NH4+ and OH-. Join Yahoo Answers and get 100 points today. e) It dissociates only slightly in water. It therefore, can't "dissociate to a slight extent," because there aren't any molecules of NH4OH to dissociate. Molecules of "ammonium hydroxide" don't exist. it dissociate slightly in water compare to a strong base like NaOH that would dissociate 100% e) It dissociates only slightly in water. = Correct Answer .... not really. ... "Strong" or "weak" refer to the degree of ionization, not concentration. weak electrolytec. Drag the appropriate items to their repective bins. d) It is only slightly soluble in water. b. does not conduct electricity. 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 cannot hold on to its hydroxide ionsd. It doesn't. a) It cannot hold on to its hydroxide ions. It is not soluble in waterc. Technically, not even (E) is correct. c. produces gas.d. Should I call the police on then? There are no molecules of NH4OH to "dissociate. Clutch Prep is not sponsored or endorsed by any college or university. What professor is this problem relevant for? I went to a Thanksgiving dinner with over 100 guests. Or if you need more Electrolytes practice, you can also practice Electrolytes practice problems. A solution containing an electrolytea. Could anyone tell me why E is right, and the others are wrong? .... Ammonia is indeed slightly soluble in water, but that is not what makes it a weak base. it is completely ionized in aqueous solution. it dissociates only slightly in watere. Password must contain at least one uppercase letter, a number and a special character. This is something you need to figure out for yourself or you won't learn anything. NH3(aq) + HOH(l) <==> NH4+ + OH- ............. Kb = 1.8x10^-5. You should be able to figure it out from that. In water, there are no NH4OH molecules to be a "weak base." If you forgot your password, you can reset it. In water, there are no NH4OH molecules to be a "weak base." Weak base show a relatively low pH compared to strong base. Molecules of "ammonium hydroxide" don't exist. = Correct Answer. it is a dilute s...as low difficulty. ", http://en.wikipedia.org/wiki/Ammonium_hydroxide. Does that mean it easily ionizes to make OH-? a. it is a dilute solution b. Get your answers by asking now. How long does this problem take to solve? nonelectrolyte. Our tutors have indicated that to solve this problem you will need to apply the Electrolytes concept. It presupposes that there are undissociated NH4OH molecules in water, and that simply isn't the case. Still have questions? c) It is a dilute solution.
