Question

Почему SiO2 не реагирует с H3PO4?

Answer 1

Ответ:

Потому что Si это кислотный элемент исключение , он физически не сможет среагировать с какой-либо кислотой , так как SiO2 по своему строению является песком

Answer 2

Ответ:  SiO2- кислотный оксид, он не взаимодействует с водой , но ему соответствует кремниевая кислота. А мы знаем , что кислотные оксиды с кислотами не реагируют.

Объяснение:

Answer 3

SiO2 (silicon dioxide) does not react with H3PO4 (phosphoric acid) because they do not have a strong affinity for each other. The chemical reaction between SiO2 and H3PO4 does not occur under normal conditions.

Source:

Silicon dioxide (SiO2) is a covalent compound composed of silicon and oxygen atoms. It is a stable compound and does not readily react with most acids, including phosphoric acid (H3PO4). Phosphoric acid is a weak acid and does not have the ability to break the strong silicon-oxygen bonds in SiO2.

However, it is worth noting that under certain extreme conditions, such as high temperatures or in the presence of catalysts, SiO2 can react with strong acids like hydrofluoric acid (HF) to form silicon tetrafluoride (SiF4) and water. This reaction is known as the etching reaction and is commonly used in the semiconductor industry for silicon wafer processing.

In summary, SiO2 does not react with H3PO4 under normal conditions due to the lack of a strong affinity between the two compounds.
