What are the 3 kinds of solubility?

Based on the concentration of solute dissolves in a solvent, solutes are categorized into highly soluble, sparingly soluble or insoluble.

Does base increase solubility?

The anion in sparingly soluble salts is often the conjugate base of a weak acid that may become protonated in solution, so the solubility of simple oxides and sulfides, both strong bases, often depends on pH. At low pH, protonation of the anion can dramatically increase the solubility of the salt.

Which of the following has maximum value of solubility product?

RbOH.

Which of the following has the maximum solubility?

Therefore, PbSO4(Ksp=1. 3×10−8) has the maximum solubility.

Which substance is maximum soluble in water?

C | OHH2-C | OHH-C | OHH2 As glycerine having more -OH group, it is highly soluble in water.

Which of the following compounds is highly soluble in water?

Owing to the high hydration energy of Be2+ (-2494kJmol-1) in forming [Be(H2O)4]2+ beryllium fluoride is very soluble in water.

Which sulphide has maximum solubility?

FeS

Which metal sulphide is soluble in excess NH3?

ZnS, MnS, FeS do not dissolve in excess NH3NH3.

What is the solubility product of AgCl?

The solubility product of silver chloride (AgCl) is 1.6 x 10-10 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.

Is sulfur metal or non metal?

Sulfur (S), also spelled sulphur, nonmetallic chemical element belonging to the oxygen group (Group 16 [VIa] of the periodic table), one of the most reactive of the elements. Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water.

What are metal sulfides used for?

Nanofibrous Materials Metal sulfide is a vital species of semiconductor materials, and shows extensive applications in catalysis, photoelectricity, photosensors, etc. However, its low electrical conductivity, as well as its poor film-forming property, remarkably limits its practical applications.

Which is not sulphide ore of metal?

Magnetite – Fe3O4; Copper glance – Cu2S. Was this answer helpful?

Which metal ore is calamine?

zinc

Are sulphide ores soluble in water?

How are sulfides formed?

Sulfide, also spelled sulphide, any of three classes of chemical compounds containing the element sulfur. Phosphine sulfides are formed from the reaction of organic phosphines with sulfur, in which the sulfur atom is linked to the phosphorus by a bond that has both covalent and ionic properties.

How many sulfides are there?

Several hundred sulfide minerals are known, but only five are sufficiently abundant accessory minerals to have been categorized as ‘rock forming’ (Bowles et al. 2011). These five are pyrite, pyrrhotite, galena, sphalerite and chalcopyrite, and it is the iron sulfides (pyrite and pyrrhotite) which are dominant.

What is the chemical symbol of Sulphur?

What is oxidised ore?

Metalliferous minerals altered by weathering and the action of surface waters, and converted, partly or wholly, into oxides, carbonates, or sulfates. These compounds are characteristic of metalliferous deposits at the surface and often to a considerable depth.

What is the sulphide ore of copper?

copper pyrite
