Explanation:
The unbalanced reaction expression is given as:
AlBr₃ + K₂SO₄ → KBr + Al₂(SO₄)₃
We need to balanced this reaction equation. Our approach is a mathematical method where we assign variable a,b,c and d as the coefficients.
aAlBr₃ + bK₂SO₄ → cKBr + dAl₂(SO₄)₃
Conserving Al; a = 2d
Br: 3a = c
K: 2b = c
S: b = 3d
O: 4b = 12d
Let a = 1, c = 3, d = b =
Multiply through by 2 to give;
a = 2, b = 3, c = 6 and d = 1
2AlBr₃ + 3K₂SO₄ → 6KBr + Al₂(SO₄)₃
