Compare And Contrast The Reaction Between Sodium Sulfate And Hydrochloric Acid

Our next goal was to confirm the identity of our compound. We accomplished this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction, we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid, and then Silver Nitrate was added. For the compound to be confirmed, a white precipitate should form again, and it did. The next reaction started with the combination of Sodium Sulfate and Ammonia Hydroxide and
This reaction also produced a white precipitate and confirmed the compound’s identity. The last precipitate reaction combined Sodium Sulfate and Potassium Hydroxide and then added Barium Chloride again. This reaction also produced a white precipitate as it should. Our last reaction contained Sodium Sulfate and Nitric Acid and then added Iron (II) Sulfate to hopefully produce a brown ring. The reaction did produce a brown ring and further confirmed our unknown substance as Sodium Sulfate. Not only did these reaction equations confirm that our ionic compound was Sodium Sulfate, but they also allowed us to see how the salt would react with different compounds and show us some of the chemical properties of Sodium Sulfate. The last goal of this project was to use gravimetric analysis to find quantitative data to use when comparing our unknown compound to Sodium Sulfate. To do this
