Question

In the following chemical reaction, what product is represented by X? (Hint: don't forget to criss cross!!!)

AlCl3 + NaOH → X + NaCl

Answer 1

Answer: AlOHsubscript 3

Explanation: this is a double replacement reaction meaning that the two reactants that are compounds switch. Al has an oxidation charge of +3 and OH has an oxidation charge of -1 it becomes subscript 3 to make it even 3 x -1 is -3. Since this is a chemical reaction you may have to balance it by using coefficients on either side of the equation. For this problem you need to use a coefficient of 3 in front of NaCl and NaOH with x being AlOHsubscript 3 since there’s only 1 OH on the reactants side.

Answer 2

Aluminum hydroxide Al(OH)3

Step-by-step explanation:

Sodium switches places with Aluminum and the new products are formed.

A balanced equation would look like this.

AlCl3 + 3NaOH → Al(OH)3 + 3NaCl
