Which element is the most reactive of Hf Cs Ba or Lu?

Cesium (Cs) is the most reactive element among Hf, Cs, Ba, and Lu. It belongs to Group 1 of the periodic table, known as the alkali metals, and tends to readily react with water and air due to its low ionization energy and high reactivity.


Why HF can not be stored in glass bottle?

HF (hydrofluoric acid) reacts with glass, which is mainly composed of silicon dioxide (SiO2), to form silicon tetrafluoride (SiF4) and water (H2O). This reaction weakens and degrades the glass, leading to potential leakage of the acid. As a result, HF is typically stored in plastic or fluoropolymer containers that are resistant to its corrosive properties.


Does hydrogen fluoride burn any container it's put in except glass?

It even is corrosive to glass!!Hydrofluoric acid attacks glass by reaction with silicon dioxide to form gaseous or water-soluble silicon fluorides. This dissolution process proceeds as follows:SiO2 + 4 HF → SiF4(g) + 2 H2OSiO2 + 6 HF → H2SiF6 + 2 H2O


What are the compounds of fluorine?

Fluorine forms a very large range of compounds since it is highly reactive (actually it is the most reactive element there is). Teflon and freon are both synthetic fluorine compounds. Fluorine salts such as potassium fluoride are used in toothpaste, or to fluoridate water.


What physical state is HF at room temp?

HF is a very corrosive gas at room temperature. It can even etch glass!


What lithography technique used in microfluidics?

Most microfluidics use "standard" lithography techniques for patterning hard substrates such as glass or silicon. This would entail spinning photoresist, then exposing and wet etching in KOH (silicon) or HF (glass) or dry etching in a reactive ion etcher or deep reactive ion etcher. Soft lithography is also common in microfluidics where a mask is created using a hard material such as patterned SU-8 or etched glass. A polymer such as PDMS is then cast on the mold to create the microfluidic features.


Is HF acid?

HF acid refers to hydrofluoric acid, which is a highly corrosive and toxic acid. It can cause severe skin burns, tissue damage, and systemic toxicity upon exposure. Special precautions, such as protective clothing and safety equipment, are necessary when handling HF acid.
