Oxalic acid, scientific name adipic acid, molecular formula: C2H2O4
Structural formula: O C-O-H
C-O-H
O Properties: Anhydrous oxalic acid is a colorless and odorless transparent crystal or white powder. Poisonous.
Soluble in water, alcohol and ether. Dihydrate is also a colorless crystal. Specific gravity, melting point 101, in dry air or when heated, it loses moisture and becomes a white powder.
Oxalic acid is a dicarboxylic acid of organic acids and one of the strongest acids among organic acids. When it reacts with concentrated sulfuric acid, it loses water and decomposes into carbon dioxide and carbon monoxide. Oxalic acid is also reducible, and oxidants are easily oxidized into carbon dioxide and water, and neutralize with alkalis to form oxalate.
Uses: In the chemical industry, it is used to manufacture pentaerythritol, cobalt oxalate, nickel oxalate, alkaline green, steel, soil analysis reagents, chemical reagents, etc. Rapid dyes are used as color development aids.
Bleaching agent for straw and straw products (oxalic acid has reducing properties), rust pollution elimination agent (oxalic acid reacts with iron to form soluble iron oxalate, which is easily washed off by water, so it can remove iron stains on the fabric).
Oxalic acid, also known as adipic acid, is the simplest diacid. (When the crystals are heated to the point where they lose their crystal water, they become anhydrous oxalic acid.) The melting point of anhydrous oxalic acid is soluble in water or ethanol and insoluble in ether.
Oxalic acid can be used to produce carbon monoxide gas by thermal decomposition in laboratories. It also contains small amounts of oxalic acid in human urine, and calcium oxalate is the main component of urethral stones. role.
You can try it, it should work. If it doesn't work, think of another way.
No matter how complete the sewer is, the municipal government will not let the feces in the bathroom be discharged directly into the pipe, but will let you settle the feces in the septic tank through the septic tank and flow into the municipal pipe.
There are several possibilities:
1. The main drainage pipe is blocked, and the water upstairs overflows; need to unclog drains; >>>More
Traditionally speaking, no, if the middle load-bearing wall of the two units at this position was originally built with the construction connected to the original, long-term leakage, the leakage of water can not flow away in time, it is possible, mainly to the actual investigation and analysis, things are not absolute have several possibilities, time observation and analysis is appropriate.
In the end, it's all mixed up. Mixed up since you came out.
