Hi, I'm Robin Higgins and this is the chemical equation for the reaction with limestone and sulphur dioxide. So when we talk about limestone, what we are really talking about is a mineral called calcium carbonate and we draw it like this for its chemical equation. So when we talk about sulphur dioxide, we could put that as S02 and so naturally, S02 shouldn't really be showing up that much but it's actually a toxin that we use and so it will get released from plants or various factories and it will turn into sulfuric acid, represented as H2S0r and so this is a really strong acid and chemical and limestone is something that's in nature as well as statues or just various buildings that we use and so this is a reaction that actually happens in acid rain. So when we combine calcium carbonate and sulfuric acid, it will actually react and create ions. So the ions that we make from this reaction are calcium 2 plus, you've got some sulfates, we create water and we create carbon dioxide. And so this is all well and good in the chemistry lab but you can see when we add sulfuric acid to calcium carbonate it really degrades it and changes it completely and so this is actually what acid rain is, it's the degradation of calcium carbonate into the ions which then, you know, would melt your statue or damage your property and whatever the limestone was made out of it would start to ruin it. And so that's pretty much the reaction and I'm Robin Higgins and this has been the chemical equation for the reaction of limestone and sulfur dioxide.
