Is chromium sulfite soluble?

Chromium Sulfide is a moderately water and acid soluble Chromium source for uses compatible with sulfates.

Why is chromium used in leather tanning?

Chromium salts, especially chrome alum and chromium(III) sulfate, are used in chromium-tanning of leather. The chromium stabilizes the leather by cross linking the collagen fibers. Chromium tanned leather can contain between 4 and 5% of chromium, which is tightly bound to the proteins.

What is the charge on chromium Cr in crn2?

Another significant oxygen compound is chromium oxide, also known as chromium sesquioxide or chromic oxide, Cr2O3, in which chromium is in the +3 oxidation state.

What is the oxidation number of SO4 3?

For example, in sulfate ion (SO42-), each oxygen has an oxidation number of -2, whereas sulfur has an oxidation number of +6.

What is oxidation number of feso4?

Accordingly, the oxidation number of Fe is +2, S is +6, and O is (-2 × 4) -8.

What is the meaning of SO4 3?

Al2(SO4)3 is a chemical compound with chemical name Aluminium sulfate. Aluminium sulfate is also called Filter Alum or Dialuminum trisulfate. It is a white crystalline solid in its anhydrous form and in its solution form it appears as a colourless liquid.

What type of reaction is Al2 SO4 3?

This is a precipitation reaction: Al 2O 3 is the formed precipitate. , Aluminium sulfate (anh.)

How do you find the factor of Al2 SO4 3?

So n factor =5*1=5.

What is the N factor of H2SO4?

n-factor of H2SO4 = 1 or 2, depending upon extent of reaction it undergoes. Although one mole of H2SO4 ahs 2 replaceable H atoms but in this reaction H2SO4 has given only one H+ ion, so its n-factor would be 1. The n-factor of H2SO4 in this reaction would be 2.

What is the N factor of ag?

(iv) For Salts: A salts reacting such that no atom of the salt undergoes any change in oxidation state. In this reaction it can be seen that the oxidation state of Ag, N, O, Mg and Cl remains the same even in the product. The n factor for such a salt is the total charge on cation or anion.

What is n factor of AgNO3?

AgNO3 – Mol. mass = 108 + 14 + 48 = 170g/mole !!! Equivalent weight = molar wt. / n- factor !!! and n factor for AgNO3 is 1 !!!

What is the Valency factor of H 3 PO 4?

Answer. Answer: N factor of is 3.
