# What is the equivalent weight of Al?

## What is the equivalent weight of Al?

The equivalent weight of an element is its gram atomic weightatomic weightformula weight, in chemistry, the sum of the atomic weights of all atoms appearing in a given chemical formula. It is generally applied to a substance that does not consist of individual molecules, such as the ionic compound sodium chloride.https://www.britannica.com › science › formula-weightformula weight | chemistry – Encyclopedia Britannica divided by its valence (combining power). Some equivalent weights are: silver (Ag), 107.868 grams (g); magnesium (Mg), 24.312/2 g; aluminum (Al), 26.9815/3 g; and sulfur (S, in forming a sulfide), 32.064/2 g.

What is the percentage of aluminium in AlCl3?

So 27 divided by 1:33.5 And we get 0.202. Since we want the mask percentage, we’re gonna multiply this number by 100 I will get 20.2%.

## What is the difference between ferrous ammonium sulphate and ammonium ferrous sulphate?

Ferrous ammonium sulfate is a pale green crystalline compound which does not effloresce like ferrous sulfate. It is less readily oxidised than FeSO4 and therefore, a better volumetric reagent in preference to ferrous sulfate. Mohr’s salt is also called as double salt which contain more than one simple salt.

What is meant by 1 gram equivalent?

Gram equivalent mass is mass of one mole of element, molecule, ion divided by their valency or number of electrons shared. It’s generally defined for either salts or metals or ions or basically compounds/atoms/molecules which can form ions.

### How do you find equivalence?

To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.

### How do we calculate equivalent weight?

Why is equivalent weight calculated?

An equivalent weight of a solution is defined as the molecular weight of the solute divided by the valence of the solute. Equivalent weight is used for predicting the mass of a substance that reacts with one atom of hydrogen in an acid-base analysis like in titration.

#### What is the oxidation number of O in Al2 SO4 3?

The oxidation number of O in Al2(SO4)3Al2(SO4)3Aluminium sulfate is a salt with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and wastewater treatment plants, and also in paper manufacturing.https://en.wikipedia.org › wiki › Aluminium_sulfateAluminium sulfate – Wikipedia is -2. The oxidation number of S in Al2(SO4)3 is +6.

#### How do you calculate the formula unit of Al2 SO4 3?

1. Given : Al₂(SO₄)₃
2. To Find : Formula unit mass of Al₂(SO₄)₃
3. Solution : Atomic mass of Aluminum (Al) = 27 u. Atomic mass of Sulphur (S) = 32 u. Atomic mass of Oxygen (O) = 16 u. ∴ The formula unit mass of Al₂(SO₄)₃ = 2×27 + 3(32 + 4×16) = 54 + 3×96. = 342 u.

What is the N factor of Al2 SO4 3?

Al 2 (SO 4 ) 3 compound consists of aluminium and sulfate ions having charges +3 and -2 respectively. These ions are symbolised as – Al3 + and SO 3- 4 . And so, the n factor for Al 2 (SO 4 ) 3 is 6.

#### How do you calculate equivalents?

Equivalent units describe how much work has been done on a certain number of physical items. To simply calculate equivalent units, you can multiply the number of physical items by the percentage of the work done on them. For two items that are 50% done, you would have one equivalent unit (2 x 50% = 1).
