I don't know the history of this question but I think the answers are meaningless. What you really want to know is "what products make a reaction go to completion?" That would be gases, ppts, slightly ionized substances.
-gases yes
-water yes
-electrons no
-precipitates
-acids yes
-ions yes but not a reason for the reaction going to completion.
-bases yes
What are three common types of products produced by reactions that occur in aqueous solutions? (out of the following)
-gases
-water
-electrons
-precipitates
-acids
-ions
-bases
3 answers
precipitates--yes
Thank you!
