This question asks you to identify the following reactions as oxidation reduction, acid base, or precipitation reaction.
00:12
It's going to be an oxidation reduction reaction if we have a change in charge.
00:17
Here we have oxygen with a 2 -minus charge going to oxygen with no charge.
00:22
So this is an oxidation reduction reaction.
00:27
Then we have sulfuric acid reacting with copper.
00:30
Here we have copper going from no charge to 2 -plus.
00:33
So another oxidation reduction reaction.
00:37
When sulfuric acid reacts with sodium hydroxide, producing the salt, sodium hydroxide, and water, it's an acid -based reaction.
00:46
Anytime we produce a salt and water, it's an acid -based reaction...
