Write balanced equations and expressions for Ksp for the dissolution of each ionic compound. a. BaSO₄

Video transcript

Hello everyone today. We are being asked to write the balanced equation and the KsB expression when magnesium chrome eight is dissolved in water. So the first thing we want to do is write out our initial substrate or our initial reactant, which is MG cr oh four. We're going to make this into a solid, We're gonna draw a reaction arrow and our products, we're going to say that this substance dissociates into one magnesium two plus ion in the acquis form As well as one chrome eight ion - in the acquis form. So that's our that's our balanced equation. When it comes to our K. S. P. It's going to be in the form of products over reactant. And so following this rule, our products we're going to have MG two plus in brackets. We're going to multiply that by the other product that we have which is C r minus. Another thing to note with KsB expressions that we don't include solids and liquids. So the original magnesium chrome eight will not be included. So we have our balanced equation and then we have our K. Sp expression. I hope this helped. And until next time
