8.2 Chemical Properties, Reactivity, pH, combustibility
Discover Chemical Properties: Reactivity, pH, and Combustibility
You will explore how substances react, burn, and interact with acids and bases and discover why these chemical properties matter in the real world.
What You'll Learn
You will learn how chemical properties describe substances changing into new materials.
You will explore reactivity through examples like rusting iron and gold stability.
You will understand combustibility and why some materials burn more easily.
You will use the pH scale to identify acids, bases, and neutral substances.
What You'll Practice
1
You will identify chemical properties like reactivity, pH, and combustibility.
2
You will distinguish between acids, bases, and neutral substances using pH.
3
You will apply knowledge of combustibility and reactivity to real-world examples.
Why This Matters
Understanding chemical properties like reactivity, pH, and combustibility helps you predict how substances behave, keep yourself safe, and make sense of the world around you.
