The conjugate acid of `OH^-` ions is ____ and conjugate base is ___

Explanation

To find the conjugate acid and conjugate base of the hydroxide ion (OH⁻), we can follow these steps:

### Step 1: Understand the Definitions
- **Conjugate Acid**: The species formed when a base accepts a proton (H⁺).
- **Conjugate Base**: The species formed when an acid donates a proton (H⁺).

### Step 2: Identify the Conjugate Acid of OH⁻
- Since OH⁻ is a base, we need to determine what happens when it accepts a proton (H⁺).
