Ionic hydrides react with water to

Options

A. Give acidic solutions
B. Give basic solutions
C. Produce hydride ions
D. Produce protons

Answer

To solve the question regarding the reaction of ionic hydrides with water, we can follow these steps:

### Step 1: Identify Ionic Hydrides
Ionic hydrides, also known as saline hydrides, are typically formed by alkali metals (Group 1) and alkaline earth metals (Group 2). The general formulas for these hydrides are:
- For alkali metals: \( MH \)
- For alkaline earth metals: \( MH_2 \)

### Step 2: Write the Reaction with Water
When ionic hydrides react with water, the following reactions occur:
- For alkali metal hydrides:
\[ MH + H_2O \rightarrow MOH + H_2 \]
- For alkaline earth metal hydrides:
\[ MH_2 + H_2O \rightarrow M(OH)_2 + H_2 \]

### Step 3: Analyze the Products
In both reactions, the products formed are:
- Metal hydroxide (either \( MOH \) or \( M(OH)_2 \))
- Hydrogen gas (\( H_2 \))

### Step 4: Determine the Nature of the Solution
Metal hydroxides are known to be basic in nature. Therefore, when ionic hydrides react with water, they produce a basic solution.

### Conclusion
Thus, the correct answer to the question "Ionic hydrides react with water to" is that they give a basic solution.

### Final Answer
Ionic hydrides react with water to give a basic solution.
