5 - Oxalic acid is one of the chemical substances with unique physical properties. It is a colorless and transparent crystal, like a prism, with a pure and crystal clear appearance. It is often in the state of a dihydrate. In this form, it contains two molecules of crystal water and has good stability.
The melting point of oxalic acid is about 101-102 ° C. This property allows it to gradually melt from solid to liquid at a specific temperature environment, realizing the transformation of the state of matter. And oxalic acid has a high solubility in water, and can be miscible with water in a certain proportion to form a uniform solution. This solubility makes it often used as a soluble reaction raw material or reagent in many chemical experiments and industrial processes.
Furthermore, although oxalic acid has no significant odor, it has a certain degree of acidity. Its acidity can turn purple litmus test solution red, which is an obvious manifestation of its acidity on the indicator. Due to its acidic properties, oxalic acid can react with a variety of metals and metal oxides to form corresponding oxalates. For example, when reacted with iron, iron oxalate compounds can be formed.
In addition, the density of oxalic acid is slightly higher than that of common liquids, at about 1.653g/cm ³. This density characteristic allows it to be separated and purified to a certain extent in solution systems or mixed substances according to density differences by physical methods such as precipitation and stratification.

What are the chemical properties of 8-hydroxyquinoline-5-sulfonic acid?

Saltpeter is a common chemical substance. Its chemical properties are unique and have many wonders.
Saltpeter, chemical name potassium nitrate, chemical formula is $KNO_ {3} $. Its appearance is usually colorless transparent orthorhombic or cubic crystal particles or white powder. From the perspective of solubility, saltpeter is very soluble in water, and can be rapidly dissociated into potassium ions ($K ^ {+} $) and nitrate ions ($NO_ {3 }^{-}$）。 This solubility allows saltpeter to play an important role in many solution reaction systems.
In terms of its oxidizability, nitrate ions are highly oxidizing in acidic environments. When encountering a reducing agent, the valence of nitrogen in nitrate ions decreases, and a reduction reaction occurs. If it encounters some metal elements, the metal can be oxidized, and the valence of nitrogen can be reduced, or nitrogen monoxide ($NO $), nitrogen dioxide ($NO_ {2} $) and other gases are formed. This oxidation is of great significance in the manufacture of gunpowder. Traditional black powder is made of saltpeter, charcoal, and sulfur mixed in a certain proportion. Saltpeter provides oxygen here, which makes charcoal and sulfur burn violently, releasing a lot of energy and achieving the power of gunpowder.
Furthermore, saltpeter is thermally stable. When heated, saltpeter will decompose, generating potassium nitrite ($KNO_ {2} $) and oxygen ($O_ {2} $). This decomposition reaction is controllable under specific conditions, and the released oxygen can support combustion. In some chemical reactions or combustion processes involving oxygen demand, saltpeter can be used as an oxygen supply agent.
In addition, saltpeter also plays a role in agriculture. Because it contains potassium and nitrogen, it can be used as a fertilizer. Potassium can enhance the lodging resistance of crops, and nitrogen is an important nutrient element for crop growth, promoting the flourishing of crops.
Saltpeter is rich in chemical properties and widely used in industry, military, agriculture and other fields. It is an important chemical substance bestowed by nature on human beings and has made a lot of contributions to the development and progress of human civilization.

What is the preparation method of 8-hydroxyquinoline-5-sulfonic acid?

The method is as follows:
First, take a number of spirit ores, which need to be pure in texture and especially rich in antimony. Wash it with clean water, remove its dust, and then place it in a crucible. Heat it slowly with a gentle fire, so that the miscellaneous gas in the mine can be exhausted, and when its color turns pure red, the fire can be stopped.
Then, prepare a pottery urn, which contains cold spring water, and the amount should be moderate. Slowly put the heated antimony ore into the urn, and instantaneously water splashes and hot steam evaporates. At this time, it is necessary to use a long-handled wooden spoon to stir quickly to ensure that the ore and water blend evenly.
When the water temperature in the urn drops slightly, take a little cyanide, grind it into a fine powder, and slowly sprinkle it into the urn. When sprinkling, be careful not to let the cyanide powder gather in one place. After sprinkling, stir it again, and see that the liquid in the urn gradually turns a faint blue color, which is a good omen.
Then, place the urn in a secret room, cover it with a black cloth, and keep it in a quiet place away from light. After seven days and seven nights, open the cloth and observe it. If you see a crystal precipitating from the bottom of the urn, this is the beginning of the form of octacyanosquare light pentaantimonic acid.
Take out the crystal again, place it on a glass dish, and bake it with a slight fire. When baking, keep your eyes on it and watch it change. When the crystal is hard in texture, lustrous in color, and seems to have a faint light, it can be made.
This octacyanosquare pentaantimonic acid is difficult to make, and it needs to be cautious step by step. If there is a slight mistake, all previous efforts will be wasted. And this material is peculiar, so be careful when using it to avoid disasters.
