Is copper sulphate white? Is copper sulphate an acid?

That's right, copper sulfate is a white powder, after encountering water, it reacts to generate copper sulfate pentahydrate cuso4*5h2o is blue, usually we call it copper sulfate crystals, this property of copper sulfate is also often used to make some chemical inference questions, so, I think, the landlord must see whether the question is given in the question is copper sulfate or copper sulfate crystal, so as not to cause calculation errors :)

Correct chemical formula CuSO4, white powder, relative density is, solubility in water at 25, insoluble in ethanol and ether, soluble in water, aqueous solution is blue, is a strong acid and weak alkali salt, due to the hydrolysis solution is weakly acidic. Copper sulfate solution is concentrated and crystallized to obtain copper sulfate blue crystals of pentahydrate, commonly known as bile alum, copper alum or blue alum, with a relative density. Bile alum is very stable at room temperature and pressure, does not deliquescent, will gradually weathered in dry air, and loses two-molecule crystal water when heated to 45, four-molecule crystal water at 110, and loses all crystal water at 150 to become anhydrous.

Anhydrous matter is also easy to absorb water and transform into bile alum. This property is often used to test for trace amounts of water in certain liquid organic compounds. When the gallum is heated to a high temperature of 650 degrees, it can be decomposed into black copper oxide, sulfur dioxide and oxygen.

Solid copper sulphate is white and blue in liquid.

Anhydrous copper sulphate is white and turns blue when exposed to water.

Copper sulphate is not an acid.

Copper sulfate is a white or off-white powder, commonly known as bile alum.

Stone gall, gall alum, blue alum.

Its aqueous solution is weakly acidic and blue. Copper sulphate is an important raw material for the preparation of other copper-containing compounds. Mix with lime milk to obtain Bordeaux liquid.

Used as a fungicide. At the same time, copper sulfate is also the electrolyte used in electrolytic refining of copper.

The common form of copper sulfate is crystalline, copper monohydrate sulfate tetrahydrate ([Cu(H2O)4]SO4·H2O, copper sulfate pentahydrate), which is a blue solid (crystal).

Precautions for the use of copper sulfate

The amount of copper sulfate is related to water fertility, organic matter and suspended solids content, salinity, and pH value.

proportional, so in the process of use, it is necessary to choose the appropriate amount according to the specific situation of the pond, and the copper sulfate should be used carefully when the water is alkaline, so as to avoid the formation of copper oxide.

Poisoning fish. The safe concentration range of copper sulfate for fish and other aquatic animals is small, and the toxicity is large (especially for fish fry), so the dosage should be accurately calculated when using, and metal utensils should not be used when dissolving, and water above 60 should be used to prevent the loss of efficacy.

Oxygen is consumed, affecting water quality and leading to flooding.

1. Anhydrous copper sulfate color: white or off-white powder. Its aqueous solution is weakly acidic and blue.

2. Color of copper sulfate pentahydrate: When copper sulfate crystallizes from aqueous solution, bright blue copper sulfate pentahydrate (CuSO4·5H2O, also known as bile alum) is generated, and this principle can be used to test the existence of water. It decomposes after losing crystal water after being heated, and is very stable at room temperature and pressure, without deliquescent, and will gradually weathered in dry air.

3. It is a protective inorganic fungicide, which is relatively safe for humans and animals. Copper sulphate is an important raw material for the preparation of other copper-containing compounds. Bordeaux liquid can be obtained by mixing with lime milk, which is used as a fungicide.

It is also used as an electrolyte for electrolytic refining of copper. Copper tetraaminohydrate can be used as a bathroom disinfectant.

1. Copper sulfate color: white or off-white powder. Its aqueous solution is weakly acidic and blue.

2. Copper sulfate (cupricsulfate), an inorganic compound, chemical formula CuSO4. It is white or grayish-white and refers to the color of the friend. The aqueous solution is weakly acidic and appears blue.

However, when crystallized from an aqueous solution, blue copper sulfate pentahydrate (CuSO4·5H2O, also known as bile alum) is generated, and this principle can be used to test the presence of water. Decomposes after losing crystal water after being heated, Weiling is very stable at room temperature and pressure, and will gradually weathered in dry air.

3. Copper sulfate is an important raw material for the preparation of other copper-containing compounds. Bordeaux liquid can be obtained by mixing with lime milk, which is used as a fungicide. It is also used as an electrolyte for electrolytic refining of copper.

1. Sodium peroxide: it is originally light yellow, but it is white when exposed to water.

2. Huling anhydrous copper sulfate: originally a white trouser book, blue when exposed to water.

3. Anhydrous cobalt chloride: originally dark blue, pink when exposed to water.

Copper sulfate is a white or off-white powder, and its aqueous solution is weakly acidic and blue. However, when crystallized from an aqueous solution, a blue copper sulfate pentahydrate (alum) is formed, a principle that can be used to test the presence of water.

The color of copper sulfate: The solid color of copper sulfate is an auspicious or off-white powder of Baizhou, and the aqueous solution is weakly acidic blue.

The general form of copper sulfate is crystalline, which is copper monohydrate sulfate tetrahydrate ((Cu(H2O4SO4·H2O, copper sulfate pentahydrate, blue solid (crystal). Because that aqueous solution will be copper ions in the mid-range state and blue, it is often used in laboratories to check the presence of copper sulfate pentahydrate in the water.

Uses: 1. Mainly used as textile mordant, agricultural insecticide, water fungicide, preservative, also used for tanning, copper plating, mineral processing, etc.

2. It is used as an astringent drug and disease prevention drug, and it is also an agricultural fungicide.

3. Used as analytical reagents, mordants and preservatives.

4. Uses: This product is the main salt of copper pyrophosphate plating. The composition is simple, the stability is good, the current efficiency is high, and the deposition speed is fast. However, its polarization force is small and its dispersion ability is poor. The coating is coarse and not shiny.

5. Use: Drip analysis of tellurium and zinc, catalyst for nitrogen determination, sugar analysis, urine and cerebrospinal fluid test, determination of serum protein, whole blood glucose, non-protein nitrogen, chromatographic analysis. Insecticide, mordant, antiseptic. Various media were prepared in haplotype species, and beef digestible soup medium was prepared in bacterial serum testing.
