Urgent! Is sodium thiosulfate in aqueous solution alkaline?

The aqueous solution is weakly alkaline and soluble in water, and it weathers in dry air above 33 and loses crystal water.

48 More than crystalline water dissolved in itself, easy to deliquescent in moist air. It is relatively stable in neutral and alkaline solutions, and will decompose rapidly in acidic solutions.

The aqueous solution of sodium thiosulfate has a pH of about 9 to 10 and is alkaline.

The aqueous solution of sodium thiosulfate is alkaline.

Thiosulfuric acid is acidic, so the corresponding alkali: sodium thiosulfate is alkaline.

Be. Because the aqueous solution of Na2S2O3 is alkaline, this is because S2O32-hydrolysis increases the concentration of OH- in the solution, so it is alkaline.

Colorless and transparent crystals, easily soluble in water, aqueous solution is weakly alkaline (S2O32-hydrolysis, which increases the concentration of OH- in the solution) Weathering and losing crystal water in dry air above 33 More than 48 soluble in its own crystal water, easy to deliquescent in humid air. It is relatively stable in medium and alkaline solutions, and will decompose rapidly in acidic solutions

It is alkaline, and 1mol L of sodium thiosulfate is about pH and has been tested before.

It is alkaline and reacts in an acidic solution to form sulfur.

The aqueous solution of sodium thiosulfate is alkaline.

Baking soda is a colorless and transparent crystal, soluble in water, and the aqueous solution is weakly alkaline It weathers in dry air above 33 and loses crystal water 48 or more dissolves in its own crystal water, which is easy to deliquescent in humid air. It is relatively stable in neutral and alkaline solutions, and will decompose rapidly in acidic solutions.

Yes, thiosulfate is a poly-weak acid acid with strong primary hydrolysis ability.

Sodium thiosulfate is alkaline. Sodium thiosulfate, also known as baking soda and hypo, is a colorless and transparent monoclinic crystal, odorless, salty, specific gravity, soluble in water, aqueous solution is nearly neutral and insoluble in alcohol, decomposes in acidic solution, has strong reducing property, and can dissolve halogens and silver salts. It is easy to weathering in dry air above 33 and deliquescent in humid air.

Use. 1. The photographic industry is used as a fixer, a reducing agent for dichromate during tanning, a neutralizer for nitrogen-containing tail gas, a mordant, a bleaching agent for wheat straw and wool, and a dechlorinating agent for pulp bleaching. It is also used in the manufacture of tetraethyl lead, dye intermediates, etc., and the extraction of silver from ores.

2. Reducing agent for electroplating industry Water purification agent for water purification project.

3. In the textile industry, it is used as a dechlorinator after bleaching of cotton fabrics, a sulfur dye for dyeing wool fabrics, an anti-whitening agent for indigo dyes, and a pulp dechlorinator.

4. It is used as detergent, disinfectant and fading agent in the pharmaceutical industry.

Sodium thiosulfate (Na2S2O3) is a common and important inorganic compound with a variety of important chemical properties, here are some of its properties:

1. Water solubility: sodium thiosulfate is easy to dissolve in water, with high solubility, and water is commonly used as a solvent in the preparation and treatment process.

2. Reducibility: sodium thiosulfate is a weak reducing agent, which can reduce certain metal ions to metals under acidic conditions, such as reducing Cu2+ to Cu.

3. Antioxidation: sodium thiosulfate can inhibit the oxidation reaction, and the thiosulfate ion (S2O3 2) can react with oxygen molecules to prevent oxygen from further reacting with other substances.

4. Stability: sodium thiosulfate can exist stably at room temperature and will not undergo spontaneous oxidation reaction. However, it is easy to decompose into sodium sulfite and sodium sulfate, so care should be taken to preserve it during use.

5. Catalytic effect: sodium thiosulfate can play a catalytic role in the reduction process, accelerate the reaction rate, and can be used to produce some chemicals.

In general, sodium thiosulfate has a variety of important chemical properties and is widely used in chemical, pharmaceutical, and photographic fields.

The properties of sodium thiosulfate are as follows:

It is a colorless and transparent crystal, soluble in water, and its aqueous solution is weakly alkaline. Sodium thiosulfate is stable under alkaline and neutral conditions, and easily decomposes under acidic conditions. Sodium thiosulfate is reductive and can be used as a ligand, in large quantities due to the fixer of photography.

Quantitative reactions with iodine can occur and are used in analytical chemistry for iodine titration.

Sodium thiosulfate, also known as sodium sulfite, baking soda, hypo (** in its alias sodium hyposulfite). Molecular formula: Na2S2O3·5H2O.

It is a common thiosulfate, colorless transparent monoclosed potato oblique crystal with a density of gram cm3. The melting point is 48 degrees Celsius at standard atmospheric pressure.

Sodium thiosulfate is colorless, transparent crystalline or crystalline fine grain; Odorless, salty taste; Efflorescence in dry air and deliquescent in humid air; Soluble in water, aqueous solution weak alkaline reaction; In case of strong acid, sulfur elemental and sulfur dioxide gas are produced.

With the participation of thiocyanase, it can combine with cyanide ions that are free in the body or bound to methemoglobin to form non-toxic thiocyanate that is excreted in urine and decentralizes cyanide poisoning. In addition, it can also combine with a variety of metal ions to form non-toxic sulfides that are excreted in the urine, and also have desensitization as a nuclear backup.

Question 1: Sodium sulfate is soluble in water endothermic or exothermic Upstairs don't mislead people, okay...

Question 2: Is sodium sulfate soluble Sodium sulfate is soluble in water, insoluble in organic solvents...

Question 3: Does sodium sulfate solid dissolve in water and absorb water The molar mass of sodium sulfate is 142g mol The amount of substance of 71 grams of sodium sulfate solid 71 142= Since Na2SO4 contains 2 Na+, the amount of substances containing sodium ions in sodium sulfate, that is, the number of Na+ is Na.
