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

Single replacement reactions involves an ionic compound or ionic-like compounds, such as acids and bases, reacting with an element or compound composed of one element. The products are an ionic compound and element. In a single replacement reaction, the cations essentially switch place if the lone element carries a positive charge in ionic compound. The anions essentially switch place if the lone element carries a negative charge in ionic compound.

The best way to approach single replacement reactions is to first label the charges of each of the ions in the ionic compound and element.

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

You are great at explaining! I actually understand now!🎉

thank you it helped me a lot in my exam

Wouldn't the sodium oxide from the first example be aqueous according to solubility rules? I thought oxides were insoluble unless the compound contains a Group 1 metal or ammonium...

i didn't understand your explanation

Why did the i in the 2nd problem automatically become i2 is that just a rule ?
