What is the ratio of al3+ ions to s2- ions in a neutral compound1:1
2:1
2:3
3:2

Answers

Answer 1
Answer:

The ratio of Al^3+ ions to S^2- ions in a neutral compound is 2:3.

The neutral compound formed by aluminum ion and sulphide ion is aluminium sulphide, with chemical formula Al2S3. Looking at the chemical equation, you will observe that, for each molecule of aluminium sulphide, there is two atoms of aluminium and three atoms of sulphur. This is the ratio of combination for the compound, that is, for every two atoms of aluminium, there are three atoms of sulphur, thus, the combination ratio is 2:3.

Answer 2
Answer: 2:3. The neutral compound formed between aluminium and sulfur is Al2S3 since aluminium has the valence 3 and sulfur is 2. So there are 2 aluminium atoms for every 3 sulfur atoms and the ratio is 2:3.
