When sodium sulfide and iron III nitrate are mixed together what is formed?

When sodium sulfide and iron III nitrate are mixed together what is formed?

Sodium sulfide reacts with acquis iron, three nitrate to form aqueous sodium nitrate and solid iron.

What happens if sodium sulfide is added to iron II sulfide?

Answer Expert Verified. If sodium sulfide is added to iron(II) sulfide, no reaction could occur since they have a common ion. Instead, in the solution, the concentration of Fe2+ would decrease while the concentration of S2- would increase since more of this ion is added from sodium sulfide.

Is FeS a precipitate?

It was observed that FeS precipitation is pseudo 1st order when Fe(II) to S(-II) concentration ratio is below 1:5, although the precipitation rate is extremely fast. At temperature range of 23 – 100 °C, freshly precipitated FeS was found to be mackinawite or amorphous FeS.

Is FeS solid?

sulphide) is one of a family chemical compounds and minerals with the approximate formula FeS. Iron sulfides are often iron-deficient non-stoichiometric. All are black, water-insoluble solids.

Is FeS a compound or element?

Iron (Fe) and sulphur (S) are two elements. When they are added together, they form a mixture of iron and sulphur. The iron and sulphur are not joined together. However, if the mixture is heated, a new compound is formed, which is called iron sulphide (FeS).

How do you separate FeS?

Answer. Mixture of Fe and S have constitutent particles of Fe and S while FES don’t have. It also can be separated by simple physical means while the compound can be separated by chemical means. The mixture have variable composition while compound have fixed composition.

What is true about FeS?

Answer. Option 3 is true about iron sulphide. Iron sulphide is black brown in colour. Iron with sulphur combine to give iron sulphide.

Why Valency of chromium is 3?

Valency is the combining capacity of an element. It is equal to the number hydrogen atoms with which one atom of a particular element combines to form its normal hydride. Hence, the valencies of chromium can be taken as 2 and 3, as in the case of iron, which is also a transition metal.

Can two cations form an ionic bond?

A proper ionic formula has a cation and an anion in it; an ionic compound is never formed between two cations only or two anions only. The key to writing proper ionic formulas is simple: the total positive charge must balance the total negative charge.

Which compound contains ionic bonds?

Table salt, NaCl, is a good example of this type of compound. Ionic bonds differ from covalent bonds. Both types result in the stable electronic states associated with the noble gases. However, in covalent bonds, the electrons are shared between the two atoms.
