What is the name of Br2?
Bromine
Is Br2 an oxidizing agent?
To help eliminate confusion, here is a mnemonic device to help you remember how to determine oxidizing and reducing agents. Br− loses an electron; it is being oxidized from Br− to Br2, thus Br− is the reducing agent. Cl2 gains one electron; it is being reduced from Cl2 to 2 Cl−, thus Cl2 is the oxidizing agent.
Is Br2 oxidized or reduced?
The half-equation is: 2Br–(aq) → Br2(l) + 2e– The chlorine gains these electrons, so it is the oxidising agent (becoming reduced to Cl– ions). The bromine has given electrons to the chlorine, so the bromide ions are the reducing agent (becoming oxidised to Br atoms, which form Br2).
Is Br2 a halogen?
Halogens The properties of chlorine (Cl2), bromine (Br2) and iodine (I2) will be observed. At room temperature chlorine is a greenish gas, bromine is a reddish/orange liquid, and iodine is a purple solid.
What is br2 oxidation number?
The most stable oxidation state of the element is −1, in which bromine occurs naturally. But oxidation states of 0 (elemental bromine, Br2), +1 (hypobromite, BrO−), +3 (bromite, BrO−2), +5 (bromate, BrO−3), and +7 (perbromate, BrO−4) are also known.

Is CuS soluble in water?
Cuprous sulfide occurs in the form of black powder or lumps and is found as the mineral chalcocite. Large quantities of the compound are obtained by heating cupric sulfide (CuS) in a stream of hydrogen. Cuprous sulfide is insoluble in water but soluble in ammonium…
Is CuS a solid?
CuS is a moderate conductor of electricity….Copper monosulfide.
| Names | |
|---|---|
| Appearance | black powder or lumps |
| Density | 4.76 g/cm3 |
| Melting point | above 500 °C (932 °F; 773 K) (decomposes) |
| Solubility in water | 0.000033 g/100 mL (18 °C) |
Is CuS a base?
Since sulfide is basic, CuS will dissolve in acidic solution. Since sulfide is basic, CuS will dissolve in acidic solution. As acid is added, this reaction is shifted towards the right.
Is CuS ionic?
Therefore, this group of copper sulfides shows ionic conductivity at slightly elevated temperatures. CuS, for example, can be written as Cu3(S2)S. Several nonstoichiometric compounds with Cu:S. ratios between 1.0 and 1.4 also contain both monosulfide as well as disulfide ions.
What does sulfide look like?
The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin. But, there are a few vitreous and transparent members such as realgar, cinnabar and orpiment that tend to break the mold, so to speak.
Is sulfur the same as sulfide?
Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions. Solutions of sulfide salts are corrosive. Hydrogen sulfide (H2S) and bisulfide (SH−) are the conjugate acids of sulfide.
Is gold a sulfide?
Gold(I) sulfide is the inorganic compound with the formula Au2S. It is the principal sulfide of gold. It decomposes to gold metal and elemental sulfur, illustrating the “nobility” of gold.
What is difference between Sulphur and sulphide?
Sulphur exists in nature in the form of sulphate, sulphite, sulphide compounds. – The oxidation state of sulphur in sulphide is ‘-2’. – The main difference between sulphite, sulphate, and sulphide is the number of oxygen atoms and the oxidation state of the sulphur present in the respective derivatives.
What is the symbol of Sulphur?
S
Is Sulphur good for the hair?
Sulfur has been proven to lengthen the growing phase of your hair. A longer growing phase (before resting and shedding) means longer hair. Lastly, sulfur also has been linked to treating, relieving, and decreasing the occurrences of psoriasis, dandruff, eczema, and folliculitis.Mehr 19, 1392 AP
What is the symbol of sulphate?
SO₄²-
What is SO4 2 called?
The anion is sulfate ion = SO4. 2-.
Why is sulfate 2?
With oxygen pulling the electrons toward itself, the sulfur gets a partial positive charge. Sulfur can have either a partial positive charge or a partial negative charge. We would need 32 valence electrons for 4 full outer shells(8×4) but only have 30. Thus the charge is 2- for the ion.
What color is sulfate?
Salts
| Name | Formula of the corresponding salts | Color |
|---|---|---|
| Copper(II) sulfate (anhydrous) | CuSO4 | White |
| Copper(II) sulfate pentahydrate | CuSO4·5H2O | Blue |
| Copper(II) benzoate | Cu(C7H5O2)2 | Blue |
| Cobalt(II) chloride | CoCl2 | Deep blue |

Is Baby Shampoo sulfate-free?
Baby shampoos are good examples of sulfate-free formulas. Instead of SLS they contain materials known as amphoteric surfactants that are less drying to skin and milder to the eye. (Hence the “no more tears” claim of many baby shampoos.
