The pH of normal KOH is

Options

A. 1
B. 0
C. 14
D. 7

Explanation

To find the pH of normal KOH, we can follow these steps:

### Step 1: Understand the nature of KOH
KOH (potassium hydroxide) is a strong base. When dissolved in water, it completely dissociates into potassium ions (K⁺) and hydroxide ions (OH⁻).

### Step 2: Determine the concentration of OH⁻ ions
In a normal solution of KOH, the concentration of KOH is typically 1 M (molar). Therefore, the concentration of OH⁻ ions in the solution will also be 1 M.

### Step 3: Calculate the pOH
The pOH can be calculated using the formula:
\[ \text{pOH} = -\log[\text{OH}^-] \]
Substituting the concentration of OH⁻:
\[ \text{pOH} = -\log[1] = 0 \]

### Step 4: Calculate the pH
The relationship between pH and pOH is given by the equation:
\[ \text{pH} + \text{pOH} = 14 \]
Now, substituting the value of pOH:
\[ \text{pH} + 0 = 14 \]
Thus,
\[ \text{pH} = 14 \]

### Conclusion
The pH of normal KOH is 14.
