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 this case the product of the ion concentrations (2.024 x 10-5) would be much greater than the Ksp (5.0 x 10-9) The solution can't hold this many ions, so the excess ones will precipitate. So, to summarize: When Trial Ksp Ksp, a precipitate will form. When Trial Ksp Ksp, a precipitate will NOT form.
