The easiest way to decide is by looking at thermodynamic stability--solid silver chloride is more stable. It can be called double displacement reaction or salt metathesis reaction, depending on who you're talking with. To analyse such situations, you first must realize that nearly everything is present as ions. How to find individual probabilities of all numbers from a list? by $\ce{NH3}$ or $\ce{CN-}$. Use MathJax to format equations. Molecular cohesion (enthalpy) is greater in AgCl than in AgNO3, thus promoting its formation. oxidize the Cl-, so that $\ce{Cl2 ^}$ is removed out of the system. Here are some interesting points for the question: Liebman concludes from thermodynamic data (and contrary to HSAB expectations) that $\ce{Ag+}$ is better solvated than $\ce{Na+}$ or $\ce{K+}$. The other answers make an error, I think. What is the ionic compound formula of ammonium sulfate? I think the reaction proceeds because the formation of AgCl(s) is enthalpically favored. Unless the message is supposed to be that reality is complicated... (which OTOH allows for the beautiy of reality and makes it interesting). What is the ionic compound formula of sodium sulfate? if I did? Can lead(II) oxidize tin metal in aqueous solution? $$\ce{Ag+_(aq) + Cl(aq)- <=>> AgCl_(s)}$$. Why do aqueous solutions of sodium chloride and silver nitrate swap ions? Why were there only 531 electoral votes in the US Presidential Election 2016? The net ionic equation however, would be: Notice, the spectator ions - which are the common ions in both sides - are removed from the net ionic equation. Why does Lovecraft write that Mount Nansen (approx. First of all, it's actually kind of an overdue homework question: It is well established in the pedagogical literature that AgCl is insoluble in water while NaCl and 9000 ft.) is 15,000 feet high? This reduces the reaction to: Now, we have reduced the question to "why does $\ce{AgCl}$ precipitate?". Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. See all questions in Ionic Bond Formation. Krishna visiting Sudra's home or touching a Sudra, How to make my own professional book step-by-step( there is a course or a book that I didn't find?). Making statements based on opinion; back them up with references or personal experience. $$\ce{Ag+ + Cl- <=> AgCl v}$$. What is the ionic compound formula of sodium phosphate? How do I know that? Is it because $\ce{Cl}$ is just one when $\ce{NO3}$ is multiple? in different solutions) put into contact will spontaneously form a precipitate. #Ag^(+)(aq) +NO_3^(-)(aq)+K^(+)(aq)+Cl^(-)(aq)->AgCl(s)+K^(+)(aq)+NO_3^(-)(aq)#. What exactly are cap_style and join_style in shapely buffer function? Maybe you can do your own research from the answers provided here and come back with a more "elaborate" answer. Silver (Ag) has a +1 charge. The reaction between silver nitrate #AgNO_3# and potassium chloride #KCl# is the following:. The easiest way to decide is by looking at thermodynamic stability--solid silver chloride is more stable. Edit the question and put the oxidation numbers to confirm that it is not a redox reaction. Aluminum has a +3 charge. Do all threads share the same instance of a heap variable, or have different instances of a heap variable? This reaction is a type of metathesis reaction. Why is that? For example, if you took the reaction $\ce{NaCl +KBr->NaBr +KCl}$, the "direction" it goes in has no real meaning since $\ce{Na+}$, $\ce{Cl-}$, $\ce{K+}$, $\ce{Br-}$ are present as ions. Why do silver nitrate and sodium hydroxide react to produce silver(I) oxide? Daisy G. asked • 10/12/19 Write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate. Here are two experiments that you can do to check that it is really a dynamic equilibrium (though much on the side of the precipitate) You may have to wait quite a while for this one, though... F'x pointed us to a paper Paradigms and Paradoxes: The Solubility of AgCl in Water. And given the insolubility of AgBr and AgI, I'd guesstimate unsoluble even though AgF is soluble (after all $\ce{F-}$ is usually different from the other 3). Identify the oxidation and reduction half-reactions. Why does potassium react more violently with water than lithium? AgCl(s) is favored due to it is has a more covalent fashion than NO3. This means Aluminum Nitrate would have the formula Al(NO3)3. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Thus, silver nitrate has the formula AgNO3. #AgNO_3(aq)+KCl(aq)->AgCl(s)+KNO_3(aq)# During this reaction, a precipitate will form which is the silver chloride #AgCl#.. If a piece of software does not specify whether it is licenced under GPL 3.0 "only" or "or-later", which variant does it "default to"? We can safely remove them from the equation. indeed this is no redox problem, oxidation states do not change. Of course, I sort of "assumed" that $\ce{AgCl}$ precipitates in the beginning--this was so that I wouldn't have to complicate stuff. rev 2020.11.24.38066, The best answers are voted up and rise to the top, Chemistry Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us, I talked to my teacher today and she said it exactly as @CHM did. around the world. Should recorded lectures be provided for students when teaching a math course online? Nitrate is NO3 with a -1 charge. Asking for help, clarification, or responding to other answers. Use the solubility rules provided in the OWL Preparation Page to determine the solubility of compounds. #Ag^(+)(aq) +NO_3^(-)(aq)+K^(+)(aq)+Cl^(-)(aq)->AgCl(s)+K^(+)(aq)+NO_3^(-)(aq)#, Net ionic equation: #Ag^(+)(aq)+Cl^(-)(aq)->AgCl(s)#. The paper estimates that the enthalpy of $\ce{AgCl_{(g)} -> AgCl_{(s)}}$ is comparable to that for the alkali chlorides.
