MDL number MFCD00043295 This information is not yet completed. Product Name: Copper(II) Sulfide Product Number: All applicable American Elements product codes, e.g. Most chlorides, bromides and iodides are soluble, except Silver and Mercury. The presence of pyrites in many ore deposits, and its reaction with water and oxygen to form iron sulfate and sulfuric acid, creates an important source of acid.

CH 3 SCH 3. IDENTIFICATION. SECTION 1. By bagus amin - Maret 07, 2018 … Suppose one wishes to separate nickel(II) ions with a concentration of 0.20 M from copper(II) ions with a concentration of 0.10 M. Although the sulfide precipitation studies conducted at Boeing were at pH 8 to 9, the sulfide precipitation of heavy metals is highly effective even at lower pH values. 4. Molecular Weight 205.58 .

CU2-S-02 , CU2-S-03 , CU2-S-04 , CU2-S-05 CAS #: 1317-40-4 Relevant identified uses of the substance: Scientific research and development Supplier details: American Elements 10884 Weyburn Ave. More information about Copper(II) sulfide (CuS).

Absorption is influenced by a number of factors including the chemical forms of copper: oxides, hydroxides, iodides, glutamates, citrates, & pyrophosphates of copper are readily absorbed, but copper sulfides & other water insoluble salts are poorly absorbed. Among the heavy metals, HgS has the lowest solubility, and ZnS and NiS have the highest solubility.

Soluble or Insoluble. Copper (II) sulfide, CuS, [1317-40-4], MW 95.6, occurs in nature as the blue-black mineral covellite, [19138-68-2]. More information about Copper(II) sulfide (CuS). View information & documentation regarding Copper(II) sulfide, including CAS, MSDS & more. The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. Solubility in .

All nitrates, acetates and perchlorates are soluble. All carbonates, sulfides, […]

This information is not yet completed. Compare the solubility of copper(I) sulfide in each of the following aqueous solutions: Clear All 0.10 M Cu(NO3)2 More soluble than in pure water 0.10 M K2S Similar solubility as in pure water 0.10 M NH4CH3COo Less soluble than in pure water.

For ionic compounds with limited solubility in water, an equilibrium constant, K sp, can be defined from the ion concentration in water from the equation:.

Beilstein/REAXYS Number 4386581 .

M m A n (s) = mM n+ (aq) + nA m-(aq).

2. In moist air, it is oxidized to copper (II) sulfate. Sigma-Aldrich offers a number of Copper(II) sulfide products.

CuS ( Copper(II) sulfide ) is Insoluble in water. 0.10 M KNO3 Submit Answer Retry Entire Group 6 more group attempts remaining

If the sulfide ion in solution exceeds the solubility of one cation and not the other, the less soluble metal sulfide precipitates (Q > K sp), and the more soluble metal sulfide remains in solution (Q K sp).

Solubility Rules: Greater than 0.1 mole/Liter = Soluble Between 0.1 and 0.01 mole/Liter = Slightly Soluble Less than 0.01 mole/Liter = Insoluble 1.
