Prepare for this practice
Classify materials by composition and use the pH scale as a measure of acidity in aqueous systems.
Review Elements, compounds, acids, and bases before starting →Ideas to recall
- Elements contain one type of atom; compounds contain chemically bonded elements.
- Mixtures retain components that can be separated physically.
- Acids and bases show characteristic behavior in water.
- The pH scale is logarithmic, so each whole step represents a tenfold change.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
