AlCl3 + NaOH = NaClO2 + Al (OH) 3

balance the equation!

*dont forget the O2 in NaClO2!

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
