A metal sulphate has the formula `MSO_` . A chloride of the same metal will have the formula

Options

A. `M_2Cl_3`
B. `M_2Cl`
C. `MCl_2`
D. `MCl`

Explanation

To determine the formula of a chloride for the metal that forms the sulfate with the formula `MSO4`, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sulfate Ion**:
The sulfate ion (SO4) has a charge of -2. This means that the metal (M) must have a charge of +2 to balance the charge in the compound MSO4.

2. **Determine the Charge of the Metal**:
Since the formula is MSO4, the metal ion (M) must have a +2 charge to balance the -2 charge from the sulfate ion. Therefore, we can conclude that the metal is a divalent metal (M^2+).

3. **Identify the Chloride Ion**:
The chloride ion (Cl) has a charge of -1.

4. **Calculate the Number of Chloride Ions Needed**:
To neutralize the +2 charge from the metal ion (M^2+), we need two chloride ions (Cl^-). This is because two -1 charges from the chloride ions will balance the +2 charge from the metal.

5. **Write the Formula for the Chloride**:
Since we have one metal ion (M) and two chloride ions (Cl), the formula for the chloride of the same metal will be MCl2.

### Final Answer:
The formula for the chloride of the same metal will be **MCl2**.
