Why is Na2CO3 pronounced as sodium carbonate instead of disodium carbonate?

Should I ask the Chemistry class representative about this?

Why isn’t Roujiamo called Mojiarou? We’re just used to calling it that.

NaHCO 3 is not pronounced as monosodium carbonate, but as sodium bicarbonate. Since there is no monosodium carbonate or trisodium carbonate, it is natural to pronounce Na 2 CO 3 as sodium carbonate, which will not cause misunderstanding.

It is just an abbreviation in case of no confusion. If there is a possibility of confusion, only the full name can be used.

Thank you. I don't understand your answer. Is it because I didn't describe the problem clearly enough?

For example, iron can be divided into ferric oxide and ferric tetroxide, so we cannot simply say iron oxide, which will cause confusion. If it does not cause confusion, we can simply say sodium carbonate.

Examples that will not cause confusion: Zinc has only one oxide, ZnO, which can be simply called zinc oxide, not monozinc oxide. Water can contain one oxygen atom or two oxygen atoms, and the one containing two oxygen atoms must be called hydrogen peroxide or hydrogen peroxide to avoid confusion.

This should be the correct answer. Since there is only one type, we usually use the simplest name.

[NaHCO3 is not pronounced as monosodium carbonate] Do you mean [NaHCO3 is not pronounced as monosodium bicarbonate]?

Thank you. Is the correct way to read Na2CO3 disodium carbonate?

[Do you mean to say [NaHCO3 is not pronounced as monosodium bicarbonate]? ]

You can understand it this way.

[The correct way to read Na2CO3 is to read it as disodium carbonate]

At least there is no such customary pronunciation, and the Chinese Chemical Society does not have similar regulations.

Western science was introduced to China in the late Qing Dynasty. The gases we now write as hydrogen, oxygen, nitrogen, and chlorine were translated as light gas, nourishing gas, light gas, and green gas at that time. It was translated as light gas because it has the lowest density; it was translated as nourishing gas because it is indispensable for all animals; it was translated as light gas because it dilutes the nourishing gas; it was translated as green gas because it is light green.

Later, the Chinese Chemical Society stipulated that the names of non-metals in solid state at room temperature should be derived from "石", solid metals from "金", liquid from "水", and gas from "气". Solid non-metals include carbon, silicon (formerly known as 矽), arsenic, sulfur, and tellurium, not to mention solid metals. There is only one liquid metal, mercury, and liquid non-metals include bromine. Gaseous light gas was changed to hydrogen, nourishing gas to oxygen, light gas to nitrogen, green gas to chlorine, and helium, neon, argon, krypton, xenon, radon, etc.

The Chinese Chemical Society did not stipulate that Na 2 CO 3 should be read as disodium carbonate, but rather as sodium carbonate, just as Si was originally called silicon and is now called silicon.

Until now, the medical community in mainland China still calls silicosis "silicosis". Although the Chemical Society has already stipulated that Si is silicon. Electronic technology has changed it.
