What is a sea wave, what is a sea wave

Hypo is a common thiosulfate, colorless transparent monoclinic crystal. Sodium thiosulfate is easily soluble in water, and reacts with strong acids to produce sulfur elemental matter and sulfur dioxide gas.

Sodium thiosulfate is an antidote to cyanide. It is colorless, transparent crystalline or crystalline fine grain; Odorless, salty taste; Efflorescence in dry air and deliquescent in humid air; The aqueous solution is weakly alkaline.

Haibo is the popular name for sodium thiosulfate pentahydrate, which is a colorless monoclinic crystal, and sodium thiosulfate is easily soluble in water.

When many people are chatting with photography professionals, they sometimes hear these professionals mention the concept of Haibo, what does Haibo mean? Let's find out.

01 Hypo is known for its use as a fixer in photography. In addition, Haibo can also be used as a pharmaceutical antidote, a dechlorinator in the paper industry, etc.

02 Hypo and baking soda are both common names for sodium thiosulfate pentahydrate. Sodium thiothiofibrine pentahydrate is a colorless monoclinic crystal, which is dissolved in its own crystal water; It is easy to weather in dry air above 33.

03 Haibo is known for its use as a fixer in photography. Because its aqueous solution is an aqueous reed, it can react with the unphotosensitive halogenated color in the film to form a water-soluble complex.

04 Hypo can be used as a cyanide antidote in medicine. Experiments have shown that the injection of hypo solution into dogs can increase the semi-lethal dose of cyanide to dogs by 3 times.

05 Haibo is used as a dechlorinator in the textile and paper industry. People use chlorine to bleach fabrics and pulp, and after bleaching, the residual chlorine needs to be removed, which can be achieved with an aqueous solution of Haibo.

1. Haibo is the common name of sodium thiosulfate pentahydrate, which is a colorless monoclinic crystal.

2. In the solution of Kaifeng in its own crystal water; It is easy to weatherize in dry air above 33 °C. Hypo is known for its use as a fixer in plexuc photography. In addition, Haibo can also be used as a pharmaceutical antidote, a dechlorinator in the paper industry, etc.

Haibo, also known as sodium thiosulfate, also known as "sub-baking soda", is a colorless and easily soluble crystal in water, but insoluble in ethanol, weathering in dry air, deliquescent in humid air; Its aqueous solution has a weak alkaline reaction.

Hypo is used as a dechlorinating agent in the textile and paper industry. Fabrics and pulp are bleached with chlorine (or chlorine-containing bleach), and the residual chlorine needs to be removed after bleaching, which can be achieved with an aqueous solution of Hypo, and then washed off the resulting acid with clean water.

Many people may not be very familiar with this substance, but those who have developed ** know that Haibo can be used as a fixer in photography, because its aqueous solution can act with the unphotosensitive halogenated color in the film to generate a water-soluble hail complex (complex) Na3 [AG(S2O3)2].

Haibo is still very widely used, can be used as an antidote, detergent, disinfectant chemical reagent in medicine, and also used in electroplating. In addition, it is also used in the manufacture of synthetic dye intermediates and organic chemicals. In addition, Haibo has also been used for some diseases.
