Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as [NH 4]Cl. It is an ammonium salt of hydrogen chloride. It consists of ammonium cations [NH 4] + and chloride anions Cl −. It is a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic.

A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...
It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia ( NH 3 ). Ammonium is also a general name for positively charged (protonated) substituted amines and quaternary ammonium cations ( [NR 4 ] + ), where one or more hydrogen atoms are ...

Lysis buffer usually contains one or more salts. The function of salts in lysis buffer is to establish an ionic strength in the buffer solution. Some of the most commonly used salts are NaCl, KCl, and (NH 4) 2 SO 4. They are usually used with a concentration between 50 and 150 mM. [4] Sodium dodecyl sulfate (SDS) structure
