Commonly referred to as ammonia or ammonia gas, the compound is used as a cleaner and in the manufacturing of plastics, rubber, fertilizers and textiles. For a list of solubility of alcohols, see https://chemed.chem.purdue.edu/genchem/topicreview/bp/2organic/alcohols.htmlFor ionic compounds, unlike Ethanol, we can use these basic rules for solubility (see https://youtu.be/zffVKN6tm7k):Salts of:- Group I elements (Li+, Na+, K+, Cs+, Rb+) are- NH4+ (Ammonium ion) are soluble.- the nitrate ion (NO3-) are generally soluble.- of Cl-, Br-, and I- are soluble. /F2 9 0 R At 0 C and 1.00 atm, as much as 0.70 g of O 2 can dissolve in 1 L of water.

For alcohols with longer chains of carbon atoms, like CH3(CH2)9OH (Decanol) much of the molecule is nonpolar (or only very slightly polar) and the molecule will therefore be insoluble in water. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. of polar solvents such water forming dipole dipole interactions can dissolve in water.
