in this video we're going to talk about how to write net ionic equations so let's consider the reaction between aqueous led to nitrate and aqueous potassium chloride now the first thing that you need to do is you need to predict the products of this chemical reaction that's the first thing now what we have here is a double replacement reaction lead is going to pair up with chlorine and potassium is going to pair up with nitrate potassium has a positive one charge nitrate has a negative one charge if the magnitude of the charges are the same then you can combine those ions in a one-to-one ratio so what are the products will be kno3 now the other product we need to pair up the lead and chloride lead has a positive two charge and we could tell based on how many nitrate ions are attached to it each nitrate ion has a minus one charge and it's two of them so to neutralize the two nitrate ions the lead has to have a positive two charge chloride has a minus one charge so when you combine these two it's going to be lead 1 CL 2 or basically just TB CL 2 now we need to write the phases of the products the potassium nitrate is its soluble or insoluble so hopefully you're familiar with your solubility rules nitrates are always soluble so therefore this is going to be an aqueous phase now what about leads to chloride does that dissolve in water or is it insoluble in water let's you chloride is insoluble the halides chloride bromide iodide they're soluble with everything except lead silver and myrrh so what we have here is a solid product now our next step is to balance the formula equation that we have here so notice that we have two nitrate ions on the left side so therefore we're going to put a 2 in front of kno3 now we have two potassium atoms on the right side so we got to put a 2 in front of KCl and we can put a 1 in front of the other ones so now we have a balanced formula equation now whenever you mix two aqueous solutions and if you get a solid product then this reaction is not only a double replacement reaction but it's also called a precipitation reaction so keep that in mind now once we have our balanced formula quai ssin we need to write the total ionic equation and the way to do that is to you need to identify every substance that is in the aqueous phase and separate them into ions the substance that is in a solid or liquid phase or anything else other than equal space you want to rewrite it exactly the way it is so let's unite rate we're going to have to decompose it into ions so we have a PV plus 2 ion and two nitrate ions...
