In this video, you'll learn how to predict the products of double replacement or double displacement reactions. We'll start with the basics of what double replacement reactions are and then go through three examples together step by step.

Double replacement reactions involves two ionic compounds or ionic-like compounds, such as acids and bases, reacting with each other. The products are two new ionic compounds. In a double replacement reaction, the cations essentially switches places with each other. You can also think of the anions switching places with each other. Both perspective is correct.

The best way to approach double replacement reactions is to first label the charges of each of the ions in the two ionic compounds.

By the end of this video, you'll know exactly how to predict the products of double replacement or double displacement reactions.

This is literally saving my life the night before a quiz.

[ADepressedwhale]

This is BY FAR the easiest method I've seen so far. Saving my ass before a big quiz. The way you explain it is so much simpler than any other video I've seen

Teacher: Teaches something
*I don't understand*
Youtube teacher: teaches something
*I now understand*

anyone else here 17 minutes before a chemistry test

Thanks a lot, sir. Today is my science exam and this video really helped me to understand what displacement reaction is. 😃

[shaneflaherty]

I missed a day of class when we taught this stuff and this video really helped me get all caught up. Thanks a bunch!

[emmanuelabrigarde]

You simplified this 10 times better then my teacher

[benkhong]

Yo….. THIS JUST HELPED ME. THANK YOU SO MUCH!

[teiadhurup]

what would the balanced equation be for the first one?

[liamdurkin]

Why dont you make the charges negative on the criss cross method

[zakmatew]

Can you please explain the last example? When you combined H3 with (OH)2 you got H2O. What happened to H3 and also (OH)2???

[joshuakim]

Why do you take only one of each element?

[a.kjfhkziujsfdgbskjxfyhgfl]

how can you determine if 2 ionic compounds will react ?

[wscoxde]

Sir may I ask why the last one is water instead of HOH😢😢😢😢😢😢😢😢😢😢

[ticagamer]

my teacher must suck, because this 6 minute video jus saved my life

[karat]

Why do u bring over some subscripts and not others? And how do u know which ones u bring over n which ones u don’t? So confusing🤨

[sams.purity]

watching this 1 hour before my ib Chem quiz ☠️

[flyboy]

You’re so fun to listen to this was so helpful thank you ;m; <3

[ruger]

Gotta do the balances too man, never do you not do them as well in a class

[anandhis]

2nd equation agbr why not agbr2 pls explain
