Details:

Copper sulphate (chemical: CuSO4), white or grayish white powder.The aqueous solution is weakly acidic and blue.But when crystallized from aqueous solution, the blue pentahydrate copper (CuSO4· 5H2O, also known as alum) can be used to test the presence of water.The heat loss of the crystalline water decomposes, stable at normal temperature and normal pressure, not deliquescence, in dry air will gradually weathering.

Copper sulfate is an important material for preparing other copper compounds.Bordeaux mixture with lime milk is used as a fungicide.Electrolyte used in electrolytic refining copper.

Physical properties

Appearance and properties: copper sulphate without water is gray white powder, easy to absorb water and blue and green acid copper sulphate.

Anhydrous copper sulfate powder

Melting point: 560 ℃.

Density: 3.606g/mL (25 DCS)

Vapor pressure: 7.3mm Hg (25 dg)

Solubility: soluble in water and methanol.Insoluble in ethanol [1]

Chemical properties

1. Easily absorb moisture from the air and become hydrate.Heating after losing crystal water, heated to 102 ℃ lost two crystallization water;113 ℃ lost three crystallization water;All 258 ℃ lose crystal water;When the heating temperature of 653 ℃, began to decompose generate CuO and SO3, at the end of the 720 ℃ decomposition.

The change of crystallization water is as follows:

The changes occurring at different temperatures are as follows:

2. A single plasmic replacement reaction, such as iron and zinc, which is located in copper before the activity sequence, cannot be replaced with an overly reactive metal (e.g. sodium, potassium, etc.).

3. Reaction with alkali

In response to ammonia water, copper hydroxide was produced in a small amount of time.

Phenomena: add a small amount of ammonia to copper sulfate solution, and have blue precipitation.Continue adding ammonia water, precipitation dissolve, generate dark blue solution.In addition to ethanol, dark blue precipitates precipitate out.
