The chemical formula of bleaching powder is

Options

A. `CaClO_(2)`
B. `CaOCl_(2)`
C. `CaOCl`
D. `CuOCl_(2)`

Answer

To determine the chemical formula of bleaching powder, we can follow these steps:

### Step 1: Identify the Common Name
Bleaching powder is commonly known as a chemical compound used for bleaching and disinfecting purposes.

**Hint:** Look for the common uses of the compound to help identify its name.

### Step 2: Determine the Chemical Name
The chemical name of bleaching powder is Calcium Oxychloride.

**Hint:** Chemical names often indicate the elements present in the compound.

### Step 3: Identify the Elements in the Compound
Bleaching powder is composed of three key elements: Calcium (Ca), Oxygen (O), and Chlorine (Cl).

**Hint:** Break down the chemical name to identify the constituent elements.

### Step 4: Count the Atoms of Each Element
From the chemical name, we can deduce the number of atoms:
- Calcium (Ca) = 1 atom
- Oxygen (O) = 1 atom
- Chlorine (Cl) = 2 atoms

**Hint:** Pay attention to the prefixes in the chemical name, as they often indicate the number of atoms.

### Step 5: Write the Chemical Formula
Combining the elements and their respective quantities, the chemical formula for bleaching powder is:
\[ \text{Ca(OCl)}_2 \]

This indicates that there is 1 Calcium atom, 1 Oxygen atom, and 2 Chlorine atoms.

**Hint:** Use parentheses to group elements when there are multiple atoms of a particular element.

### Final Answer
The chemical formula of bleaching powder is \( \text{Ca(OCl)}_2 \).
