Which catalyst is the best for the reaction betweeen Aluminum metal and HCl?

AI Thread Summary
The discussion centers on identifying the best catalyst among copper sulfate, sodium chloride, potassium iodide, and magnesium sulfate for the reaction between aluminum metal and hydrochloric acid. The chemical equation for the reaction is provided, showing the formation of aluminum chloride and hydrogen gas. There is a belief that copper sulfate may be effective based on a prior experiment, but clarity is sought on how each salt acts as a catalyst. Participants are encouraged to discuss the properties that make these salts potential catalysts and their mechanisms of action. Understanding these factors is crucial for determining the most effective catalyst for this reaction.

1. I need to know which compound out of Copper Sulfate, sodium chloride, potassium iodide and magnesium sulfate will be the best catalyst for the reaction between ALuminum metal and Hydrochloric acid.



2. The chemical equation is : 2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)



3. I believe that copper sulfate would do the trick because my teacher showed us an experiment in which copper sulfate was used but I am not sure.

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
