Identify chemicals based on their uses (recall)

Google Classroom
This article is a fun self-checking activity you can use to recall the uses of chemicals obtained from common salt.
Here, we will not ask questions in the usual way. Instead, we will solve "Who am I?" puzzles. Solving puzzles are a fun way to learn the facts you need in chemistry.
So, let's get started!
Hi! We are chemicals (or salts) that you come across in daily life. We have lots of applications. Some of us are used in the kitchen for cooking, in detergents for washing, in hospitals, etc.
Let's see if you can identify each one of us by knowing our applications.
Let's begin!

Who am I?
