“Constant dripping wears away the stone,” and so it is with chemistry knowledge. Consistent practice is key, especially when it comes to reading chemical names. 9th grade is a crucial stepping stone, laying the foundation for high school chemistry. So, how can you conquer the “fear” of reading chemical names in 9th grade? Let’s explore with “HỌC LÀM”!

First Steps: Mastering the Rules
Just like learning Vietnamese, to read chemical names correctly, you need to master the rules. The rules for reading chemical names in 9th grade revolve around identifying valence, acid radicals, and base radicals. It might seem “confusing as anything” at first, but don’t worry, “if at first you don’t succeed, try, try again.” With diligent practice, you’ll find it “as easy as pie.”
Rules for Reading Oxide Names
Oxides are divided into two types: basic oxides and acidic oxides. Basic oxides are read according to the formula: “Metal name (with valence if the metal has multiple valences) + oxide.” For example: FeO (iron (II) oxide), Fe2O3 (iron (III) oxide). Acidic oxides are read according to the formula: “Nonmetal name (with prefix indicating the number of atoms) + oxide.” For example: SO2 (sulfur dioxide), SO3 (sulfur trioxide).
Rules for Reading Base Names
Bases are read according to the formula: “Metal name (with valence if the metal has multiple valences) + hydroxide.” For example: NaOH (sodium hydroxide), Fe(OH)2 (iron (II) hydroxide). Ms. Nguyen Thi Lan, a renowned chemistry teacher at Tran Phu Secondary School in Hanoi, once said: “Persistence is the key to success in chemistry.”
Rules for Reading Acid Names
Acids are read according to the formula: “Acid + nonmetal name (prefixes and suffixes indicating oxygen count may be added) + hydric (for oxygen-free acids).” For example: HCl (hydrochloric acid), H2SO4 (sulfuric acid). Reading acid names requires meticulousness and accuracy. Just like recording secondary school academic transcripts, care and precision are needed.

Regular Practice
“Practice makes perfect.” Learning to read chemical names is not a one-day affair. Practice regularly with exercises in textbooks, workbooks, and reference materials. You can also refer to how to read chemical names in 11th grade for a broader perspective: cách đọc tên hóa học lớp 11.
Real-World Applications
Knowing how to read chemical names not only helps you achieve high scores in tests but also helps you understand the world around you better. For example, when reading product labels, you will better understand the ingredients of that product.
Conclusion
“The beginning is always the hardest,” but with persistence and the right learning methods, you can completely conquer reading chemical names in 9th grade. Remember to practice regularly and don’t hesitate to ask your teachers and friends questions.
