Because the acidity of sulfuric acid is greater than that of hydrogen sulfate, the reaction can occur according to the law of forced weak reaction. Because of its large solubility product, FeS can be dissolved in strong acid solution for metathesis reaction.
If it reacts with concentrated sulfuric acid, the result will be very different, because concentrated sulfuric acid has strong oxidation, which will oxidize S element in FeS into S simple substance.
To learn chemistry well, here are some suggestions:
Cultivate interest in chemistry: chemistry is an interesting subject, and understanding and cultivating interest in chemistry is the first step to learn chemistry well. You can cultivate your interest by reading chemistry-related books and paying attention to chemistry news and experiments.
Master basic knowledge: The key to learning chemistry well is to master basic knowledge. To start learning chemistry, we should start with the basic knowledge, including the periodic table of elements, atomic structure, chemical bonds and so on. It is suggested that you take notes during the study to facilitate review and review.
Integrating theory with practice: Chemistry is an experimental science, and practice is an important means to learn chemistry well. Taking part in experimental courses or projects while studying chemistry is helpful to consolidate and understand theoretical knowledge. At the same time, we should abide by the safety rules and pay attention to the accuracy and meticulousness of the experimental operation.
Consolidate knowledge by doing problems: chemistry is a subject that needs to be understood and applied, and knowledge can be consolidated by solving problems. You can find related problem sets and practice according to different chapters to strengthen your understanding and memory of knowledge points.
Participate in discussions and exchanges: participating in discussions and exchanges can broaden the understanding of chemistry. You can participate in extracurricular activities related to chemistry, attend academic seminars or join academic societies. And share your learning experience and opinions with others.
Resource utilization: There are many chemistry learning resources available now, such as chemistry textbooks, online open classes, academic papers and scientific research documents. Make full use of these resources to expand the understanding and learning of chemical knowledge.
Perseverance: Learning chemistry well requires persistent efforts. Chemistry is a subject that needs repeated training and mastery. We should persist in studying, be diligent in practice, and constantly improve our understanding and ability.
In short, learning chemistry well requires interest, basic knowledge, practical experience, problem-solving ability and continuous efforts. I believe that as long as you pay enough time and energy, you can understand and master chemistry knowledge and become an excellent chemistry learner.
