Chapter 4: Elements, Compounds, and Mixtures Chemistry: What we hope to do in chemistry We hope to experiment with different substances to determine changes in the mixtures.

= Solution Lab =

Purpose: will different compounds form solutions in water.

IV: Types of compound  ·  Copper Sulfate  ·  Zinc Oxide  ·  Sulfur  ·  Sodium Chloride  ·  Sucrose DV: Ability to dissolve in water

Constants:  ·  Amount of water - 20  ·  Type of water  ·  Temperature of water  ·  Number of mixes - 5 Procedures: 1. Measure 20 ml of water. 2. Place a small amount (tip of lab scoop) of each compound in a separate test tube. 3. Add the water to the test tube and record observations. 4. Mix the test tube 5 times and record observations. After: Dissolved || 1. yes 2. Yes 3. Yes 4. Yes || After: Cloudy; Opaque; White || 1. Yes 2. No 3. No 4. No || After: Stayed the same || 1. No 2. No 3. No 4. No || After: Transparent, dissolved || 1. Yes 2. Yes 3. Yes 4. Yes || After: Same || 1. Yes 2. Yes 3. Yes 4.Yes || Observation words: Opaque, Homogeneous, Translucent, Transparent, Uniform, Heterogeous
 * Compound || Observations || Dissolved ||
 * Copper Sulfate || Before: Crystals are staying at the bottom
 * Zinc Oxide || Before: Cloudy; White
 * Sulfer || Before: Floating on sides, top, bottom
 * Sodium Chloride || Before: Transparent, particles spread out
 * Sucrose || Before: Transparent, particles at bottom

Vocabulary:

 * 1) Insoluble
 * 2) Soluble
 * 3) Solvent
 * 4) Solute
 * 5) Solution
 * 6) Dissolve

Pupose: What happenens to the temperature when a solute dissolves in a solvent.

IV: Amount of sodium chloride (g)

DV: Temperature

Constants:
 * 1) Type of solute
 * 2) Amount of water - 50ml
 * 3) Amount of solute - 1 (g)
