Potassium is a very reactive metal, but in compounds it is present as the potassium ion and is not very reactive. For example, dry potassium bicarbonate powder can be used to extinguish burning liquids. Why is there such a difference in the reactivity of potassium metal and the potassium ion?
A. The potassium in the bicarbonate salt is a base, but the potassium metal is an acid.
B. The potassium in the bicarbonate salt is an acid, but the potassium metal is a base.
C. The combustion of the liquids suppresses the potassium's ability to react.
D. The potassium metal can readily ionize by losing its one valence electron; the potassium in the bicarbonate salt is already ionized.
E. The potassium atom is bonded to an oxygen atom in the bicarbonate salt, but in the metal it is unbound and free to react.

- List four common laboratory bases and their uses.arrow_forwardYour lab assignment presentation involves putting together a presentation to show other students on how to perform titration. In other words, your presentation can be used to show other students (next term) how they can perform a titration by following your instructions and calculations. To do this presentation, we are giving you the type of acid, acetic acid, the type of base, NaOH to be used, and you will use phenolphthalein as the indicator. You will use the data given to you to be used as an example of how to solve the mathematical calculations. At the end of your presentation, you will show the unknown concentration of the acetic acid (Molarity) and will also show the % mass/ vol of the Vinegar solution.
