11.5: Batteries
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

Since hydrofluoric acid (HF) will eat through just about anything…
First, HF (hydrofluoric acid) has the property that it can eat through glass. Glass is mainly SiO 2, and since no element but F has the ability to dislodge oxygen from its bond, glass containers are used for all sorts of acids (HCl, H 2 SO 4, HNO 3). HF can react with glass, so it doesn''t work there.

It holds its own against acetic acid at room temperature and performs well with citric acid. Yet, not all acids are treated equally by silicone. It does not resist hydrofluoric acid at 5% concentration, and its resistance to nitric, sulfuric, and hydrochloric acid is limited, especially at higher concentrations.

Safe Use of HF
3) Don a new pair of chemical resistant gloves (to prevent possible secondary HF burns) and massage calcium gluconate gel (2.5%) freely into the affected site. Apply the gel as soon as the washing is done. The affected area does not need to be dried first. The gel will turn white (CaF 2 precipitate) upon reaction with the acid. OR
The Acidity of the Hydrogen Halides
By contrast, the estimated K a for hydrofluoric acid is small. Hydrofluoric acid only ionizes to a limited extent in water. Therefore, it is a weak acid. The estimated value for HF in the table can be compared to the experimental value: Experimental value: 5.6 x 10-4 mol dm-3; Estimated value: 1.6 x 10-3 mol dm-3
About the dangers of lithium-ion batteries
When electrolytes are burned (vinyl carbonate and propylene carbonate are burned), other toxic gases (mainly carbon oxides) are formed. To prevent the battery from leaking or burning, lithium-ion batteries must be handled with extreme care. If an electrolyte leaks from the lithium-ion battery, the liquid may contain hydrofluoric acid.

Thus, you wont make a more corrosive acid by putting F- into an acid, the F- doesn''t want to take the H+ ions. If the acid is stronger than HF, you''ll make the acid weaker by adding F- by dilution. If the acid is weaker than HF, the F- won''t accept H+ from the weaker acid because the F- is more stable without the H+.
