Question

How many fluoride ions (F-1) are needed to balance an aluminum ion (Al+3)?

Answer 1

The correct answer is that we need three fluoride ions (F-1) to balance the compound.

Step-by-step explanation:

Hello!

Let's solve this!

For the compound to be balanced, the charges have to be balanced.

We have +3 loads of Al and -1 of F.

We must multiply by 3 the Fluor so that it is as follows:

+ 3 + 3 * (- 1) = + 3-3 = 0

Therefore, we conclude that the correct answer is that we need three fluoride ions (F-1) to balance the compound.

Answer 2

WHen aluminum ions are added to fluoride ions, they form aluminum fluoride (AlF3). In this respect, when aluminum fluoride dissociates in water, it releases 3 fluoride ions and one aluminum ion. The answer is 3 fluoride ions.
