Discussion Overview

The discussion revolves around the identification and creation of red or yellow precipitates using specific chemicals, including cobalt chloride, calcium hydroxide, iron, sodium carbonate, iron sulphate, and copper sulphate. Participants explore potential chemical reactions and combinations that could yield such precipitates.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant requests examples of red or yellow precipitates that can be formed from a specified list of chemicals.
  • Another participant suggests that the requester should conduct experiments themselves, implying that hands-on experience is valuable in chemistry.
  • A different participant mentions that Wikipedia can be a resource for searching possible chemical combinations.
  • One participant notes that iron oxide is red and sulfur is yellow, encouraging experimentation to discover how to produce these compounds.
  • There is a suggestion that applying electricity could facilitate chemical reactions, either by overcoming natural reaction biases or by accelerating them.

Areas of Agreement / Disagreement

Participants do not reach a consensus on specific examples of precipitates, and the discussion remains exploratory with various suggestions and approaches presented.

Contextual Notes

Participants express different methods for achieving the desired chemical reactions, but specific procedural details and conditions for successful outcomes are not fully outlined.

Who May Find This Useful

This discussion may be of interest to chemistry students, educators, and hobbyists looking to explore chemical reactions and precipitate formation.

Can anyone give me an example of a red or yellow precipitate that can be made out of any of the following: Cobalt chloride, calcium hydroxide, iron, sodium carbonate, iron sulphate or copper sulphate. Or any chemical that can be made out of these e.g. sodium hydroxide, copper hydroxide, etc? Sounds a bit random, I know, but just out of interest, I would like to know (also, I would like to use the rest of these chemicals:smile:).
 
Chemistry news on Phys.org
This is much more fun if you do it yourself! Do you have access to a CRC Handbook of Chemistry and Physics? Any edition will do...
 
He has access to Wikipedia though. Just search the different possible combinations.
 
iron oxide is red, sulfur is yellow, how to get them is your venture.
start mixing things, apply electricity if needed, heat, cold, whatever it takes. Thats how chemists become chemists. themoreyou do the more you learn
electricity is very useful tool, it can force reactions against their natural bias or speed them up considerably
