Answer:

Al (Aluminum)

Al (OH)₃

Explanation:

Reaction Given:

                 AlCl₃ + NaOH -------> X (OH)₃ + NaCl

As we see at the reactants there are to compounds combining together

that is Aluminum Chloride and Sodium hydroxide.

Reaction Reactant:

AlCl₃

NaOH

This reaction is type of double displacement.

Now

if we look at the product side we again have 2 types of products

Reaction Products

1. X(OH)₃

2. NaCl

So,

Also according to law of definite composition a chemical compound  have fixed ratio of component in product.

So, If we look at both the reactant and product atoms in compounds only Aluminum (Al) is missing on the product side.

Also if we look at the product i.e. X(OH)₃ means that 3 OH groups are combine with an atom that have the tendency of combining with 3 OH group and have valency of 3.

So only aluminum have the 3+ valency and can form a compound with OH have 3 at its base in unit formula.

So,

The product will be

Al (OH)₃

And the balanced chemical reaction will be

   AlCl₃ + 3NaOH -------> Al(OH)₃ + 3NaCl
