Molecular, Ionic, and Net Ionic Equations

Күн бұрын027 - Molecular, Ionic and, Net Ionic Equations
In this video Paul Andersen shows you how to write balanced equations that describe chemical changes. He then gives you a short introduction to balancing equations and uses the PHET site to practice this skill. In aqueous solutions an ionic equation (or complete ionic equation) is helpful in following the ions. When the spectator ions are removed a net ionic equation can be used to show the chemicals that are actually combining in the reaction.

As a fellow chemistry teacher, I appreciate using your videos as additional resources. They are great! However, there are two errors in this video. The net ionic equation should show only 1 mole of lead II iodide (should not have a coefficient of 2 in the equation). Also, the descriptor for the ppt is incorrect and should be listed as (s) and not (aq). Love your videos :)

I listen to your videos in the car whilst going to work ( not watching of course unless at a red light) and the recording quality is good so that despite the noise of traffic i can clearly hear everything , so many thanks for this high quality and impressive biology lessons database !

I am pretty sure there are two mistakes for the net ionic equation: 1. Pb2+ + 2I- --> 2PbI2 does not make sense, it is not balance. Should it be: Pb2+ + 2I- --> PbI2 2. Since PbI2 is a precipitate, it should be PbI2(s). Every equation except for the net ionic equation write that correctly, but the net ionic equation writes it as PbI2(aq). I am not trying to be a jerk about this, but I just wanted to let you know. If I am mistaken, could you please explain why? Thank you.

On your net ionic equation, where you have Pb + 2I --> 2PbI2 shouldn't it say (s) after the product instead of (aq) since we were talking about a precipitate?

For your Net Ionic Equation, shouldn't you Lead Iodide say (s) for solid instead of (aq) because it's the precipitate? Also so do you have to balance your reaction in the molecular equation and then again in the net ionic equation? Edit: Forget that last question, in the net ionic equation, the 2 next to the Lead Iodide is just a typo right? (It's already balanced without it).

Hello Sir, what type of Ionic reaction would this be: Na2CO3 + 2H[+] ----> 2Na[+] + CO2 + H2O I'm not sure if I balanced that right. Also, what is the state (l, s, g, aq) of each compound? Na2CO3 (?) + 2H[+] (?) ----> 2Na[+] (?) + CO2 (?) + H2O (?) Thank you.
@TheTrollUnit 10 жыл бұрын
When Iodide is mixed with the following cations the solubility is low which results in a precipitate to be formed. Ag+, Pb^2+,Hg2^2, Cu+, Ti+. All other elements that form a compound with Iodide will dissolve. Hope that helped! For future questions you can search for a table that shows you the rules. " Solubility Rules for Ionic Compounds in Water"
