I previously posted this question, but I was unsatisfied with the response. Arrange the following aqueous solutions, all at 25 C, in order of decreasing acidity. Rank from most acidic to most basic. To rank items as equivalent, overlap them pH=5.45, pOH=8.55, 0.0023 M HCl, 0.0018 M KOH
Part A:Part B: Predict whether aqueous solutions of the following compounds will be acidic, basic or neutral. If the solution would be acidic or basic, circle the ion that causes the pH to change. a) NH Brb ) FeCl, c) K,CO, d) KCIO e) NaBr f) MgCl, g) NaF h) LiNO Two unknown acid solutions are both labelled 0.50 M. How could you determine which is the strong acid and which is the weak acid? Explain.
