Homogeneous Mixtures (Solids)

Question 1

Matter

Answer 1

• A substance that OCCUPIES SPACE and HAS MASS
• Classified into:
  1. Pure substances
  2. Mixtures

Question 2

Mixtures

Answer 2

• Product of two or more substances that are PHYSICALLY combined.
• Retains original properties

Question 3

Properties of solutions

Answer 3

• Made of 2 or more substances combined together
• Solute + Solvent = Solution
• Appear to be in ONE PHASE (homogeneous)

Question 4

• Solute

Answer 4

Solid/liquid/gaseous substance is dissolved

• Amount affects consentration
• ⬆️solute ⬆️concentration
  ⬆️solute ⬆️ concentration

Question 5

• Solvent

Answer 5

• Solid/liquid/gaseous substance where solute is dissolved

🔘 Water: universal solvent

Question 6

• Dissolution

Answer 6

• Process of making solutions

Question 7

• Soluble/Immiscible

Answer 7

• Dissolving ability of substance
• Refers to SOLUBILITY: in specific amounts

Question 8

• Miscible/ Immiscible

Answer 8

• Refers to mixing substances in any amount

According to phase

• Solid Solutions
  🔘 Alloys = Metals + another element

EXAMPLE:

🔴🔴🔴 ⬅️ (Metals) 🔵🔵🔵⬅️(Alloys)

Question 9

• Liquid Solutions

Answer 9

• Two substances mixed.

Question 10

• Gaseous Solutions

Answer 10

• Two substances mixed and form gaseous solutions.

Question 11

• SATURATION

Answer 11

• Amount of solute that can be dissolved in a solvent
• Three levels based on saturation point. (maximum)
  1. Unsaturated
  2. Saturated
  3. Supersaturated

Question 12

• Unsaturated

Answer 12

• Amount of solute dissolved is less than the maximum that can be dissolved in the solvent.

Question 13

Saturated

Answer 13

• Amount of solute dissolved is the maximum that can be dissolved in the solvent.

Question 14

• Supersaturated

Answer 14

• Amount of solute added is more than the maximum amount that can be dissolved
• Required additional solvent or heat to dissolve.
