 How to balance the following equation?

AlCl3 + H2O ---- Al (OH)3 + HCl

While balancing an equation, we need to make sure that the number of atoms of all the elements are same on both the sides of the equation that is the reactant side and the product side. In the said equation

 AlCl3 + H2O → Al(OH)3 + HCl

the number of atoms of all the elements except aluminium are unequal on the reactant side as well as the product side. Thus, the above equation is unbalanced. Let us start with balancing the number of Cl atoms first. There are 3 Cl atoms on the left side of the equation and one Cl atom on the right side of the equation. Thus, if we write 3 in front of HCl, the number of Cl atoms on both the sides of the equation become equal. The equation becomes 

 AlCl3 + H2O → Al(OH)3 + 3HCl

However, the number of H atoms are still unbalanced. They can be balanced if we simply write 3 in front of H2O, signifying that 3 molecules of H2O are used in the reaction. Thus, the equation becomes

 AlCl3 + 3H2O → Al(OH)3 + 3HCl

The above equation is now balanced.

First u willhave to make a table consising of elements, Reactants and Products. Likewise, write each element under the element colomn and check how many elements in the reactants side and product side. Keep on ading no.s till the elemnts get balanced.

Here, if u do tht wae u wll get AlCl3+3H2O gives Al(OH)3+ 3HCl.

Al is one on both sides

Cl is 3 on both sides

H is6 on both sides

O is 3on both sides.

Hope u hve understood.
