Harvest the onions and the greens when they are at your preferred size and flavor. Keep in mind that you can also just pick up a cheap package of scallions from your farmerâs market or grocery store if you canât find regular sets of them from your nursery.
ionic compound precipitate from a solution of the constituent ions is when the solution is basic or acid. first the ionic compound is allowed to dissociate into ions, when almost all the ions are dissociated a strong acid or base is added to change the ph, in order to precipitate the ions
In chemistry, an ionic compound is a chemical compound in which ions are held together in a structure by electrostatic forces termed ionic bonds.The positively charged ions are called cations and the negatively charged ions are called anions.onic compounds without the acidic hydrogen ion (H +), or the basic ions hydroxide (OH â) or oxide (O 2â), are also known as salts and can be formed by acid-base reactions. Ionic compounds containing hydrogen ions are classified as acids and compounds containing hydroxide or oxide ions are classified as bases.
