The compounds containing ionic bonds are known as ionic compounds. They are formed by the transfer of electrons from one atom to another. The ionic compounds are made up of positively charged ions (cations) and negatively charged ions (anions).
Cations and anions present in sodium hydroxide are

Options

A. `Na^(+) and O^(2-)`
B. `Na^(+) and O^(3-)`
C. `Na^(+) and OH^(-)`
D. `Na and OH^(-)`

Answer

To determine the cations and anions present in sodium hydroxide (NaOH), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Formula of Sodium Hydroxide**:
The chemical formula for sodium hydroxide is NaOH.

2. **Break Down the Components**:
Sodium hydroxide consists of two parts: sodium (Na) and hydroxide (OH).

3. **Determine the Charge of Sodium (Na)**:
Sodium (Na) is an alkali metal and typically forms a cation with a +1 charge. Therefore, Na is the cation in this compound.

4. **Determine the Charge of Hydroxide (OH)**:
The hydroxide ion (OH) is a polyatomic ion that carries a -1 charge. Thus, OH is the anion in this compound.

5. **Conclude the Ions Present**:
In sodium hydroxide (NaOH), the cation is Na⁺ (sodium ion) and the anion is OH⁻ (hydroxide ion).

### Final Answer:
The cations and anions present in sodium hydroxide (NaOH) are:
- Cation: Na⁺ (sodium ion)
- Anion: OH⁻ (hydroxide ion)
