Properties of Matter: Investigation 2 - Density and Chemical Reactivity
In Investigation Two, students will calculate the density of six unknown substances then observe these substances undergo a chemical reaction. During this Investigation, students will:
- Calculate the density of six unknown substances using the mass and volume recorded from Investigation 1 using the formula: mass/volume.
- Observe six unknown substances undergo a chemical reaction when placed in iron chloride, acetic acid, or silver nitrate.
Properties of Matter: Investigation 3 - Solubility and Miscibility
In Investigation Three, students will explore the solubility and miscibility of several substances in water. During this Investigation, students will:
- Observe whether five solid compounds are soluble in water or not.
- Observe whether three liquid compounds are miscible in water or not.
Properties of Matter: Investigation 4 - Compounds and pH
In Investigation Four, students will explore the pH of several solid and liquid compounds. During this Investigation, students will:
- Determine the pH of several liquid and solid compounds in solution.
- Identified each solution as acidic, neutral, or alkaline (basic).
