What is Lithium sulfate?
Lithium sulfate is a white inorganic salt with the formula Li2SO4. It is the lithium salt of sulfuric acid.
Lithium sulfate is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature, as its dissolution is an endothermic process. This property is shared with few inorganic compounds, such as the lanthanoid sulfates.
Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However, they do suffer in this application because of their water solubility.

What is Lithium amide?
Lithium amide is an inorganic compound with the chemical formula Li+NH2-, i.e. it is composed of a lithium cation, and the conjugate base of ammonia. It is a white solid with a tetragonal crystal structure.
lithium amide may refer to lithium salts of amines e.g. Li+NR2-. An example of a lithium amide is lithium diisopropylamide (LDA), which is quite commonly used.
Lithium amide can be made by adding lithium metal to liquid ammonia
Lithium amides are very reactive compounds and can act as strong bases. Unless the nitrogen atom is hindered, as in the case of LDA, they can also act as nucleophiles.

What is Sodium Bromide used for?
Sodium bromide is an inorganic compound with the formula NaBr. It is a high-melting white, crystalline solid that resembles sodium chloride. It is a widely used source of the bromide ion and has many applications.
Applications
Medicine: Known as Sedoneural, sodium bromide has been used as a hypnotic, anticonvulsant, and sedative in medicine.
bromine compounds: Sodium bromide is widely used for the preparation of other bromides in organic synthesis and other areas. It is a source of the bromide nucleophile.
Disinfectant: NaBr is used in conjunction with chlorine as a disinfectant for swimming pools.
Petroleum industry: Sodium bromide is used to prepare dense fluids used in oil wells.
