added to a carbonate solution and an effervescent reaction would confirm the presence of carbonate anions. Another sample of carbonate solution was to be reacted with hydrochloric acid and the gaseous product was to be reacted with a suspended drop of barium carbonate. The presence of clouding in the droplet would also confirm the presence of carbonate anions. Silver nitrate was to be added to chloride solution and the

identified it to be iron as it gave a yellow colour during the flame test narrowing it down to be barium or iron(iii). It then produced a yellow precipitate during sodium hydroxide test showing that it was iron(iii) instead of barium. The chemical equation for this reaction is: Fe2(SO4)3(aq) + NaOH(aq) Fe(OH)3(s) + Na2SO4(aq) I identified it as being a sulphate as it produced a white precipitate during the barium chloride test‚ indicating that sulphate ions are present.

predicated‚ the element that was found to match that of Case Study B was Barium Chloride. These results supported both the hypothesis and prediction for that was the original chemical thought to be in this case study. Barium Chloride was matched up to this case study for one‚ the flame that was produced from the mystery chemical was the same as that of Barium Chloride. When further research was conducted‚ one can see that Barium Chloride can be lethal when exposed to water as stated on the notes that

this purpose was accomplished‚ because I was able to see examples of synthesis‚ single replacement‚ double replacement‚ and combustion. I concluded that in some double replacement reactions‚ there can be a result of a precipitate‚ for example between Barium nitrate and Sodium hydroxide there was a product of a form of salt. This experiment was probably not very reliable due to the fact‚ the reactions were not done over again and double replacement was not done at the same time as the other reactions

What is the Identity of this Hydrate? Date Performed: May 30‚ 12 Date Submitted: June 6‚ 2012 Name: 2968 Instructor: Reid A hydrate was given to our group and the identity of the hydrate was unknown. The lab workers were told to determine the identity of the unknown hydrate. The identity of the hydrate could be determined by calculating the hydrate’s percent of water. So the lab workers set out to determine the water percent of the unknown hydrate. The percent of any compound or element
