One Question per Day on the Basic Knowledge of Compound Fertilizers and Functional Fertilizers – 109

Thread Content

True or False: 1. It appears as white or slightly gray crystals with an ammonia odor. It has strong hygroscopicity and is soluble in water; rubbing a small amount of the sample with your fingers releases a strong ammonia odor. When a fertilizer sample is placed directly on a red-hot iron plate, it does not melt but instead decomposes, producing a large amount of white smoke and a strong ammonia smell; this type of fertilizer is ammonium bicarbonate. ( )2. It appears as white or slightly yellow crystals, is soluble in water, has a high water absorption capacity, and tends to clump together. When a small amount of this substance is heated over a flame, a strong pungent odor is emitted along with white smoke; it melts rapidly and disappears completely. During the melting process, the unmelted portion appears yellow. This fertilizer is ammonium chloride. ( ) In the compound fertilizers and functional fertilizers section, a daily quiz on basic production knowledge is carried out. We hope that all fellow learners will participate actively. The purpose of this activity is to review the knowledge we have already learned, and to improve and strengthen everyone’s fundamental theoretical knowledge through answering questions, thereby reinforcing what we already know and helping us recall what we have forgotten. The top 50 answerers will definitely receive a reward. Please reply with the answer hidden; otherwise it will be invalid.
