What is the charge of Al2?

What is the charge of Al2?

1 Expert Answer Al has a 3+ charge, and SO4 has a 2- charge. So, it takes 3 of the SO4 anions to balance 2 of the Al cations. So, you get Al2(SO4)3.

What is the charge of Al in Al2 SO4 3?

The aluminumcation has a charge of 3+ (Al3+ ), while the sulfate anion (SO42- ) has a 2- negative charge.

How many anions are in Al2 SO4 3?

Then, in a formula unit of Al2(SO4)3 there are two aluminum ions and three sulfate ions; or two aluminum, three sulfur, and twelve oxygen atoms.

Why is Al2 SO4 3?

Aluminium sulfate is an ionic compound, a combination of both positive and negative ions. Aluminium forms a + 3 ion, Al+3, and sulphate is the -2 polyatomic ion, (SO4)-2.

What is the N factor of Aluminium sulphate?

So n factor =5*1=5.

What is alum used for?

It is aluminum potassium sulfate. This is the type of alum that you find in the grocery store for pickling and in baking powder. It is also used in leather tanning, as a flocculant in water purification, as an ingredient in aftershave and as a treatment to fireproof textiles.

Is Al2 ionic or covalent?

Aluminum Sulfate is ionic.

What is the charge of Al2 SO4 3?

1 Expert Answer. Al has a 3+ charge, and SO4 has a 2- charge. So, it takes 3 of the SO4 anions to balance 2 of the Al cations. So, you get Al2(SO4)3.

What kind of ion is aluminium sulphate Al2?

Ions are charged atoms, which may either be monatomic ions (single atoms) or polyatomic (multiple atoms combined to form a charged part). Aluminium forms a + 3 ion, Al+3, and sulphate is the -2 polyatomic ion, (SO4)-2. How dangerous is aluminium sulfate?

How does aluminium sulfate react with sodium bicarbonate?

Aluminium sulfate reacts with sodium bicarbonate to which foam stabilizer has been added, producing carbon dioxide for fire-extinguishing foams : The carbon dioxide is trapped by the foam stabilizer and creates a thick foam which will float on top of hydrocarbon fuels and seal off access to atmospheric oxygen, smothering the fire.
