Question

Use the processes of desalination (obtaining drinking water from seawater) and electrolysis of water (using electricity to separate water into hydrogen and oxygen) to explain the difference between compounds and mixtures.

Answer 1

what part do you need help with?

Answer 2

This entire question. I don't understand it and I don't remember learning about it lol @aaronq

Answer 3

lol i mean, you can look up what the terms desalination and electrolysis mean you dont really need me to do that... if you need to bounce some ideas off someone or clarify something you dont understand then you can ask away.

Answer 4

@aaronq I already included the definitions in this question... I don't know how to explain the differences of compounds and mixtures using those two processes.

Answer 5

So sea water has a lot of different salts (like NaCl, MgSO4), the desalination process is the removal of dissolved solids (e.g. ions) from it (typically by reverse osmosis). You're separating water from the mixture by removing the ions. The key here is that you're not breaking any covalent bonds, so the compounds you are left with are unchanged. That is, water is still water, NaCl is still NaCl.

Electrolysis breaks covalent bonds, between H and O in water, by supplying electrons to reduce them (in terms of oxidation state).

Answer 6

Thank you :-)

Answer 7

no problem :)
