Why can't you prepare and store tollens' reagent in advance for tests?
Tollens' reagent is made by mixing two solutions - silver nitrate and ammonia - right before use because the reaction is sensitive to light, air, and temperature, which can degrade the reagent quickly. Preparing it in advance may lead to a loss of effectiveness, affecting the results of tests. Therefore, it is best to prepare Tollens' reagent fresh when needed for accurate testing.
