Good day, great tense. In this case, we're going to be looking at the precipitation reactions of sulfate and carbonate ions. So let's look at the taste for sulfate ions. In this case, we're going to be using barium nitrate and nitric acid. So if you saw in that, in this case, they added barium chloride and nitrate, but it makes a difference. So the reaction equation is the barium two plus plus your sulfate plus a nitrate forms barium sulfate. But that is your sulfate ionic taste. And you'll notice that it formed a white precipitate which did not dissolve when we added nitric acid. Now let's look for taste carbonate. So we're going to add hydrochloric acid to carbonate ions. And then we're going to take the gas that we find and we're going to bubble it through lime water. If it goes milky, that means that we form carbon dioxide, and that means that there are carbonate ions present. So let's look at the taste. So let's look at the taste. And just the lime water. Right. So in that reaction, you saw that you added the hydrochloric acid to the carbonate ions. So we had the hydrochloric acid to the carbonate ions. We ended up with carbon dioxide plus potassium chloride plus in this because it was the potassium carbonate and water. Then if we took that gas and we dissolved it into your lime water, you end up with calcium carbonate, which is a solid. And that is why you end up with this milky precipitate. And that's how we know that we've got carbonate ions. So right, I hope that you have learned a little bit about how to taste with sulfates and carbonates. Please make sure you learn it and that you can actually explain to somebody else how to taste for them. Thank you, great tens. Have a great day.
