Mixtures and Solutions - Homogeneous Mixture

Question 1

solutions

Answer 1

• homogeneous mixtures of tow or more substances
• solute: the substance dissolved
• solvent: the substance doing the dissolving, in excess
• nine types of solutions are theoretically possible using the three states of matter
• most common solutions are those in which the solvent is the liquid water
• particles are uniformly distributed among the solvent particles throughout the solution
• solute particles will not settle out
• the solution has the same chemical and physical properties in every part

Question 2

homogeneous mixtures

Answer 2

• they are solutions
• gas-gas: air
• gas-liquid: soft drink
• liquid-gas: humidity
• liquid-liquid: wine and water
• solid-liquid: salt water
• solid-solid: metal alloys
• liquid-solid: dental fillings-mercury in silver

Question 3

solubility

Answer 3

• how much solute can dissolve in a given amount of solvent at a given temperature
• quantitative: maximum amount of solute/amount of solvent
• qualitative: soluble or insoluble

Question 4

solution terminology

Answer 4

• miscible: dissolve in each other in all proportions

- immiscible: wont mix together

Question 5

solutions,_______ colloids, _______ light

Answer 5

• unlike, will not scatter

Answer 7

• insoluble

Question 8
