WebAmines react with HC l to form amine salts, such as ethylammonium chloride. C2H5NH2 + HCl → C2H5NH3+Cl-. base acid salt. Like ammonium salts, amine salts are soluble ionic compounds, so when the alkyl group is small they are water soluble but become less so as the carbon chain increases. We can show the reaction in Brønsted-Lowry terms ... WebStep one - Convert mass into moles. Step two - To find the smallest whole-number ratio, divide by the smallest whole number. Step 3 - Write the empirical formula. Hydrated salts. -Many coloured crystals are hydrated - water molecules are part of their crystalline structure. -This water is known as water of crystallisation.
