Linseed oil, also known as flaxseed oil, is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum).The oil is obtained by pressing, sometimes followed by solvent extraction.Linseed oil is a drying oil, meaning it can polymerize into a solid form.ue to its polymer-forming properties, linseed oil can be used on its own or blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum.
Ammonia is a compound with the formula NH3, it is a weak base. Ammonium is a polyatomic ion with the formula NH4+.The ammonium ion is formed when ammonia reacts with an acid and is itself mildly acidic. because it is positively charged is is not found on its own but accompanied by a negative ion such as in ammonium nitrate, NH4NO3.mmonia is a compound with the formula NH3, it is a weak base. Ammonium is a polyatomic ion with the formula NH4+.
It is formed by the protonation of ammonia (NH 3). Ammonium is also a general name for positively charged or protonated substituted amines and quaternary ammonium cations (NR 4 +), where one or more hydrogen atoms are replaced by organic groups (indicated by R).n example of a reaction forming an ammonium ion is that between dimethylamine, (CH 3) 2 NH, and an acid, to give the dimethylaminium cation, (CH 3) 2 NH + 2 : Quaternary ammonium cations have four organic groups attached to the nitrogen atom. They lack a hydrogen atom bonded to the nitrogen atom.
