Answer to Question #104537 in General Chemistry for Kenrick Lee

Question

Describe a simple test based on what you have learned in this activity that could be used to help you identify the white powder and the thief.

Answer 1

It all depends on what kind of substance was analyzed.

So, first you need to dissolve the substance. If it dissolves, check the reaction of the medium, preferably with phenolphthalein indicator. If the color of the solution has changed to raspberry, then we have an alkali. If the substance has dissolved, but the color of the indicator has not changed, or the substance has not dissolved, then it is necessary to treat it with a solution of a strong acid (optimally, chloride) and see if gas is released.

It all depends on what was studied. Various other options are possible.
