Which of the following Statement (s) is/are correct?

Options

A. `B_(2)O_(3)` and `SiO_(2)` are acidic in nature and are important constituents of glass.
B. Borides and Silicid are hydrolysed by water forming boranes and Silanes respectively.
C. Diborane on reaction with chlorine (g) forms `B_(2)H_(5)Cl`
D. `SiO_(4)^(4-)` gets hydrolysed by acid or water and form `Si_(2)O_(7)^(6-)`

Explanation

To determine which statements are correct regarding the properties of certain compounds, we will analyze each statement one by one.

### Step 1: Analyze Statement 1
**Statement:** B2O3 and SiO2 are acidic in nature and are important constituents of glass.

- **Analysis:**
- B2O3 (Boric oxide) is indeed an acidic oxide, as it is derived from a non-metal (Boron).
- SiO2 (Silicon dioxide) can act as an acid and is also a significant component of glass.
- Major components of glass include B2O3 and SiO2, along with some phosphorus pentoxide.

**Conclusion:** This statement is **correct**.

### Step 2: Analyze Statement 2
**Statement:** Borides and silicides are hydrolyzed to form boranes and silanes respectively.

- **Analysis:**
- Borides are compounds of boron with less electronegative elements, and when they undergo hydrolysis, they can form boranes (general formula BxHy).
- Silicides are compounds of silicon with less electronegative elements, and they hydrolyze to form silanes (general formula SiH4).

**Conclusion:** This statement is **correct**.

### Step 3: Analyze Statement 3
**Statement:** Diborane on reaction with chlorine forms B2H5Cl.

- **Analysis:**
- Diborane (B2H6) reacts with chlorine to form boron trichloride (BCl3) and hydrogen chloride (HCl), not B2H5Cl.

**Conclusion:** This statement is **incorrect**.

### Step 4: Analyze Statement 4
**Statement:** SiO4^4- gets hydrolyzed by acid or water and forms Si2O7^6-.

- **Analysis:**
- SiO4^4- (orthosilicate) can undergo hydrolysis to form Si2O7^6- (pyrosilicate) in the presence of acid or water.

**Conclusion:** This statement is **correct**.

### Final Summary:
- **Correct Statements:** 1, 2, and 4.
- **Incorrect Statement:** 3.
