Split Notes for Chemical Properties Key Terms 1.What is a chemical property? 2. What is reactivity? Explanations, Definitions, and Concepts 1.A chemical property is a property that, when changed produces one or more new substances. A chemical property will cause two substances to react. 2.Reactivity is the ability of two substances to react and produce a new substance.

Split Notes for Chemical Properties Key Terms 3.What are some chemical properties? 4.What is flammability? 5.What is neutralization? Explanations, Definitions, and Concepts 3.Some chemical properties include: a.Flammability b.Oxidation c.pH and neutralization 4. Flammability is the ability of a substance to burn. 5. Neutralization is the process by which two substances, an acid and a base, combine to form a salt.

Split Notes for Chemical Properties Key Terms 6.What is an acid? 7.What are some characteristics of acids? Explanations, Definitions, and Concepts 6.An acid is a substance that has a high concentration of hydrogen ions. 7.Some characteristics of acids are: a. Sour taste b. High concentration of hydrogen ions c. Turn red litmus paper blue.

Split Notes for Chemical Properties Key Terms 8.What is a Base? 9.What are some characteristics of bases? Explanations, Definitions, and Concepts 8.A base is a substance with a high concentration of hydroxide ions. 9.Some characteristics of bases are: a. Bases are slippery. b. Bases turn blue litmus paper red. c. Bases are caustic and will burn your skin.

Split Notes for Chemical Properties Key Terms 8.What is an indicator? 9.Name a natural indicator. Explanations, Definitions, and Concepts 8.An indicator is a substance which, when placed in the presence of an acid or base, will change colors. 9.One natural indicator is red cabbage juice indicator. Red cabbage juice indicator will turn pink in the presence of an acid and green in the presence of a base.

Split Notes for Chemical Properties Key Terms 10.What is a pH scale? 11.What is acidic on the pH scale? Explanations, Definitions, and Concepts 10.The pH scale is a scale that indicates whether a substance is an acid or a base. 11.Substances that are acidic on the pH scale will turn red litmus paper blue. The scale will show that the pH (number of hydrogen ions released) is less than 7. The smaller the number, the more acidic the substance.

Split Notes for Chemical Properties Key Terms 12.What is the base score on the pH scale? 13.What is neutral on the pH scale? Explanations, Definitions, and Concepts 12.The highest basic number is 14. The higher the pH number, the more basic the substance. 13.Neutral on the pH scale is 7.
