What is the molar solubility in water of Ag2CrO4?

What is the molar solubility in water of Ag2CrO4?

The molar solubility of Ag2CrO4 in water is 6.5 x 10-5 M.

What will be the solubility of AgCl?

Answers. The solubility of silver chloride, AgCl, is 1.26 x 10-5 M at 25 °C. The solubility of barium fluoride, BaF2, is 3.14 x 10-3 M at 25 °C.

What is metal sulphide?

Metal sulfides are a major group of minerals that provide the crystal chemist a rich field for investigation due to their diverse structural types. They are abundant and cheap since they usually exist in nature as minerals such as heazlewoodite (Ni3S2), chalcocite (Cu2S), pyrite (FeS2) and so on.

What happens when metal sulphides are heated?

Most metal, except mercury, silver and gold, combine with oxygen to form metal oxides when heated.

Why reduction of metal sulphides is difficult?

Solution : The standard free energies of formation, ΔfGӨ of most of the sulphides are more negative than those of CS2 and H2S (CS2, in fact, is an endothermic compound). Therefore, neither carbon nor hydrogen can reduce metal sulphides to metal.

Which metal ion has the highest tendency to form sulphides?

As mentioned above, the characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).

Which metal occurs as a sulphide?

lead

Which metal can be extracted from bauxite?

Bauxite ore is the world’s primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions.

Which metal can be extracted from Calamine?

zinc

Which will prefer to occur as sulphide?

The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures. This is a high-symmetry structure characteristic of the iron sulfide, pyrite (FeS2O).

Are sulphides soluble in water?

The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water.
