The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Lithium acetate is used in the laboratory as buffer for gel electrophoresis of DNA and RNA. It has a lower electrical conductivity and can be run at higher speeds than can gels made from TAE buffer (5-30V/cm as compared to 5-10V/cm). At a given voltage, the heat generation and thus the gel temperature is much lower than with TAE buffers ...
The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and
Lithium peroxide is the inorganic compound with the formula Li 2 O 2. Lithium peroxide is a white solid, and unlike most other alkali metal peroxides, it is nonhygroscopic . Because of its high oxygen:mass and oxygen:volume ratios, the solid has been used to remove CO 2 from and release O 2 to the atmosphere in spacecraft .
The majority of hydrogen peroxide solutions are 3% hydrogen peroxide. [1] This enables the solution to break down any proteins that coat the contacts after a long period of use. Hydrogen peroxide is always used alongside a neutralizing product. [2] The intention is to prevent the hydrogen peroxide from contact with the eye, which could damage ...
A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture. A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution (NH 4 OH, or NH 3 (aq)), and 30% hydrogen peroxide.
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
Sodium peroxide (Na 2 O 2) is used to oxidize the sample that becomes soluble in a diluted acid solution. This method allows complete dissolution of numerous refractory compounds like chromite , magnetite , ilmenite , rutile , and even silicon , carbides , alloys , noble metals and materials with high sulfide contents.
