    AlCl₃ + 3NaOH → 3NaCl + Al (OH) ₃

    Explanation:

    Problem is to balance the given chemical equation:

    Equation:

    AlCl₃ + NaOH → NaClO₂ + Al (OH) ₃

    Balancing a chemical equation involves the conservation of atoms on both sides of the equation.

    We can use a very simple mathematical method to balance the above equation;

    aAlCl₃ + bNaOH → cNaCl + dAl (OH) ₃

    a, b, c and d are coefficients that will balance the equation:

    Conserving Al: a = d

    Cl: 3a = c

    Na: b = c

    O: b = 3d

    H: b = 3d

    Assume that a = 1;

    c = 3

    b = 3

    d = 1

    AlCl₃ + 3NaOH → 3NaCl + Al (OH) ₃

    O₂ in from of the NaClO₂ flouts the rule of chemical combination
