Question

xcl3 is the chloride of a metal x. state the formula of its(i)sulphate(ii) hydroxide of the metal
​

Answer 1

Answer:

XCl

XCl 2

XCl 2

XCl 2 =>x+2(−1)=>x=+2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4 Metal Hydroxide formula => X(OH)

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4 Metal Hydroxide formula => X(OH) 2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4 Metal Hydroxide formula => X(OH) 2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4 Metal Hydroxide formula => X(OH) 2

XCl 2 =>x+2(−1)=>x=+2Oxidation state of metal = +2metal ion X +2 Metal sulphate formula=> XSO 4 Metal Hydroxide formula => X(OH) 2 Option C is correct.

Answer 2

Answer:

The formula of metal sulphate and the formula of metal hydroxide is Al₂(SO₄)₃ and Al(OH)₃ respectively.

Explanation:

The formula of chloride of the metal: XCl₃

We know that the charge on Cl = -1

∴ X(-3)=0

∴X=3

The metal aluminium has an oxidation state of +3

Therefore, the metal is aluminium

The formula of aluminium sulphate = Al₂(SO₄)₃

The formula of aluminium hydroxide = Al(OH)₃
