Iodized common salt is

Options

A. homogeneous mixture
B. heterogeneous mixture
C. pure substance
D. oxidized substance.

Explanation

To determine what iodized common salt is, we can follow these steps:

### Step 1: Understand the Composition of Iodized Common Salt
Iodized common salt is a mixture of sodium chloride (table salt) and iodine. The iodine is added to prevent iodine deficiency in the diet.

**Hint:** Consider what components make up iodized salt and how they interact.

### Step 2: Identify the Type of Mixture
A mixture can be classified as either homogeneous or heterogeneous. A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has distinct, separate components.

**Hint:** Think about whether the components of iodized salt are evenly distributed or if they can be seen separately.

### Step 3: Analyze the Distribution of Particles
In iodized common salt, the particles of sodium chloride and iodine are uniformly distributed. This means that every sample taken from the iodized salt will have the same proportion of salt and iodine.

**Hint:** Ask yourself if you can see the individual components when looking at iodized salt.

### Step 4: Conclusion on the Type of Mixture
Since the composition of iodine and salt is fixed throughout and there are no visible boundaries between the components, iodized common salt is classified as a homogeneous mixture.

**Hint:** Remember that a homogeneous mixture appears the same throughout, which is true for iodized salt.

### Final Answer
Iodized common salt is a homogeneous mixture.
