00:01 Hi there.

00:02 This question is about neutralization reactions, and neutralization reactions are a special type of double displacement reactions.

00:18 So, again, neutralization is a type of double displacement.

00:23 In neutralization, we have an acid reacting with a base.

00:36 Both of these are aquaous, and we produce a salt, which is an ionic compound, and water.

00:49 Or of course, h2o.

00:51 So we are looking for the ones, the equations that follow this basic pattern.

00:56 All right.

00:57 So the first one qualifies, even though they have the acid and the base reversed, that doesn't matter.

01:03 We have calcium hydroxide.

01:06 It's aquaous, but i'm going to leave those out just in the interest of keeping this under 10 minutes.

01:13 C2, h3 ,02.

01:17 So that's acetic acid and calcium hydroxide.

01:20 They are reacting to form calcium acetate, which is the ionic compound here, and liquid water.

01:36 So that one is a neutralization reaction.

01:40 We see the acid and the base producing a salt and water.

01:50 Okay, so we've got one.

01:52 Let's see what else we have.

01:53 The next one, we have a double displacement reaction, but it is not.

02:00 A neutralization.

02:02 So it's a double displacement.

02:04 The compounds are switching ions, but we don't see an acid...
