AI Thread Summary
The discussion revolves around three chemistry questions related to the identification of anions and cations based on their reactions in solution. The first question involves silver nitrate forming a precipitate that dissolves in concentrated ammonia, indicating the presence of chloride ions in the original solution. The second question describes the evolution of a gas upon adding dilute hydrochloric acid, which, when passed through calcium hydroxide, forms a white precipitate, suggesting the presence of carbonate ions. The third question concerns a blue aqueous solution that produces a precipitate upon the addition of dilute hydrochloric acid, which dissolves upon heating, indicating the presence of copper(II) ions and possibly iron(II) ions. Participants express the need for study materials and hints to prepare for lab work, emphasizing the importance of memorizing relevant information. The thread also includes a comment about the relevance of the original post, suggesting a disconnect in the conversation.

Can someone help with these questions:

a)Silver nitrate is added to a solution and a precipitate forms. This precipitate dissolves when concentrated ammonia is added. What anion was present in the original solution?
b)When dilute hydrochloric acid is added to a solution, a gas is evolved. If this gas is passed through a solution containing calcium hydroxide, a white precipitate forms. What anion was present in the original solution?
c)You are provided an aqueous solution which is blue. Addition of dilute hydrochloric acid produces a precipitate. The precipitate dissolves when the solution is heated to boiling. What two cations were in the original solution?

Thanks.
 
Chemistry news on Phys.org
surely you would get a table of anions and colour precipitate, with whether it dissolves completely in conc. ammonia.
 
No, these questions we have to answer b4 going to the lab. So can someone give a hint on how to answer them?
THanks.
 
I hope u got the sheet which u hav to mugup ... lol and giv 1/2 hr daily 2 study tht ...hope it helps ! :devil:

First post? So you apparently created an account just to write a unintelligible response to a post that's from five years ago?
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
