92: The accompanying photo shows the reaction between a solution of Cd(NO3)2 and one of Na2S. (a) What is the identity of the precipitate? (b) What ions remain in solution? (c) Write the net ionic equation for the reaction, (d) Is this a redox reaction?
Step 1 of 3
Solution: Here, we are going to identify the precipitate and ions in the given solution. Also, we are going to write the net ionic equation for the reaction and identify whether it is a redox reaction or not. Step1: a) Cadmium nitrate[Cd(NO ) ] reacts wi3 2dium sulfide(Na S) to form cadmium 2 sulfide(CdS) and sodium nitrate(NaNO ). The balanced molecular equation for the 3 above reaction is : Cd(NO ) 3 2+ Na S(aq)2------> CdS(s) + 2NaNO (aq) 3 Using the guidelines of solubility, we can say that CdS in insoluble in water and will be precipitated out. Thus, the precipitate formed is CdS. Step2: b) In the above reaction CdS is precipitated out and thus only the ions of NaNO remains 3 in solution. + - Thus, Na and NO ions are3emained in the solution. Step3: c) While writing...
