Solution Composition --Concentration of a Solution--

Vocabulary Dilution Concentrated Solute Solvent solution solutions ppm.

Solutions. Aim:To investigate solubility of some compounds. Method: Water + copper(II) carbonate Water + copper(II) chloride Water + potassium chloride.

Solubility. Soluble Sugar is soluble in water. Translation: Sugar dissolves in water. The solute particles are more attracted to the solvent than they.

Aim: How do Osmosis and Diffusion compare? DN: Explain the difference between passive and active transport. HW: Page 199 #33-34.

Notes:Color Guide Gold : Important concept. Write this down. Orange : Definition. Write this down. Blue : Important information, but you do not need to.

What is a solution?  A well-mixed mixture that contains a solvent and a solute.  The solvent is the largest amount of the mixture, usually liquid, but.

Solubility Chapter 17 & 18. Solutions  Solutions are made of a solute and a solvent.  In this chapter we are concentrating on solutions of water. 

Movement Through The Cell Membrane. How Things Move in and Out of the Cell The cell membrane is selectively permeable, allowing some substances, but not.

Solubility. Solubility When a substance dissolves in another substance, it is said to be soluble When a substance dissolves in another substance, it is.

 Solutions Solutes, Solvents & Solutions. Mixtures  You should be able to recall what a mixture is.  Two or more substances that are mixed together.

Physical Change A change that alters the form or appearance of a substance but does NOT make the material into another substance –Example: ripping paper,

Solutions, Suspensions Colloids. Solutions Appears to be a single substance but really two or more substances dissolved in a solvent and evenly distributed.

…within the cell.  Movement of molecules from a high concentration to low concentration.  why does this happen?  What is it called when concentration.

Research -Natural History: distribution, use, etc. -Taxonomy (sci. name) -Anatomy or structure -Metabolic needs -Comparisons to grass.

Transport across Plasma membranes. Membranes Are differentially permeable – Permeable to SOME substances. The membrane selects what substances pass through.

Solubility. Q What is solubility? A: Solubility is the maximum amount of a solute which can dissolve in a given amount of solvent at a fixed temperature.

Objective 6.0 Define solution in terms of solute and solvent (5 EQT questions)

Chapter 18 Solutions and Crystallisation Solution – A solid dissolved in a liquid e.g. seawater Can you think of other solutions?

Chemistry. What is Chemistry? Chemistry is the study of matter and the changes that place in matter. Matter is anything that takes up space and has mass.

Solutions. Solutions  a Homogeneous Mixture –two or more substances that are distributed evenly throughout the mixture –Appears to be a single substance.

Solving Problems with Solutes and Solvents Solutions Solving Problems with Solutes and Solvents

Solution A liquid with a solute dissolved in it Can have color, but usually transparent Molecules dissolved are so small light waves do not bounce off of them lemonade tea salt water

Solute Molecules that are dissolved in a solvent to make a solution. Sugar Salt CO2

Solvent The liquid in which the solute is dissolved. Water Gasoline Acetone (nail polish remover) Turpentine (paint thinner)

Concentrated A lot of solute in the solvent

examples… Strong tea Strong lemonade Orange Juice Concentrate

Dilute Little solute in a lot of solvent

examples… weak tea weak lemonade Orange Juice from Concentrate

Soluble vs. Insoluble Soluble - able to dissolve Insoluble - not able to dissolve

Determining % Concentration 90 red (kool aid) 10 white (water) = 90% kool aid solution Solute 90 (red) Solution 100 (total) = 90 %

Determining % Concentration 50 red (kool aid) 50 white (water) = 50% kool aid solution Solute 50 (red) Solution 100 (total) = 50 %

Determining % Concentration 20 red (kool aid) 80 white (water) = 20% kool aid solution Solute 20 (red) Solution 100 (total) = 20 %

diffusion Both diffusion and osmosis happen because of differences in % concentration. osmosis
