The enthalpy of neutralisation of a strong acid by a strong base is `-57.32 kJ mol^(-1)`. The enthalpy of formation of water is `-285.84 kJ mol^(-1)`. The enthalpy of formation of hydroxyl ion is

Options

A. `+228.52 kJ mol^(-1)`
B. `-114.26 kJ mol^(-1)`
C. `-228.52 kJ mol^(-1)`
D. `+114.2 kJ mol^(-1)`

Explanation

To find the enthalpy of formation of the hydroxyl ion (OH⁻), we will follow these steps:

### Step 1: Write the Neutralization Reaction
The neutralization of a strong acid (H⁺) by a strong base (OH⁻) can be represented as:
\[ \text{H}^+ + \text{OH}^- \rightarrow \text{H}_2\text{O} \]
The enthalpy change for this reaction is given as:
...
