Define the following: Suspension Colloid Brownian motion Tyndall effect Soluble Insoluble Miscible Immiscible Concentration Molarity Dilution
Name the type of colloid: Milk Fog Hairspray Whip cream Marshmallow Butter Blood Rubies
What is the percent solution (by volume) when 50. mL of ethanol is diluted to 140 mL with water?
What is the percent by mass of 21.0 g of sodium acetate mixed with 40.0 g of water
What mass of lithium chloride is found in 85 g of a 25% by mass solution
Calculate the molarity of a solution made by dissolving 20. g of NaOH in enough water to make 5.0 Litres of solution?
Calculate the number of moles of sucrose, needed to prepare 10.0 L of a 0.50 M solution.
Calculate the number of liters of KClO 3 which would be needed to prepare of a 0.010 M solution with 0.002 mols
Full strength hydrochloric acid is 11.6 M. How many liters of this concentrated solution is required to make 1.0 L of a 1.0 M solution?
MOLARITY – Ch 13, p. 412 Quantifies the concentration of a solution.
Solution Concentration. Calculations of Solution Concentration Mole fraction Mole fraction – the ratio of moles of solute to total moles of solution.
Practice: Know your vocabulary!
SOLUTIONS Chapter 15.
Concentration of Solutions. Concentration is a measure of the amount of solute dissolved in a solution. There are many ways to measure the concentration.
1 Chapter 10 Acids and Bases 10.10Dilutions. 2 Dilution Diluting a solution Is the addition of water. Decreases concentration. ConcentratedDilutedSolution.
Solution Concentration. Calculations of Solution Concentration: Mass Percent Mass percent Mass percent is the ratio of mass units of solute to mass units.
Dilutions and Percent Solutions
Chapter 13: Solutions.
Examples-Molarity and Dilutions. Example What is the molarity of a solution that contains 4.5 moles of sucrose in L of water?
Solutions Calculations. Questions 1.What mass of NaOH is needed to make 350 mL of 0.45 mol/L NaOH solution? 2.What is the molarity if 25 g of KClO 3 is.
Solution Concentration Section 14.2 Concentration - amount of solute dissolved in a specific amount of solvent concentrated - a lot of solute dilute.
Preparing a Molar Solution
1 SOLUTIONS A N I NTRODUCTION. 2 Objectives 1. What are different ways of expressing the concentration of a solution? When is each used?
Solutions Chapter 14. solution Homogeneous mixture of 2 or more substances in a single physical state –particles in a solution are very small –particles.
Notes 15.2 Describing Solution Composition. Mass Percent Mass percent= mass of solute X 100 mass of solution = grams of solute X 100 grams of solute +
a measure of the amount of solute that is dissolved in a given quantity of solvent unit of measurement is Molarity (M) which is moles/liter can be dilute.
Concentration Units: Terms like “dilute” and “concentrated” are not specific. Percent by Mass: Mass % = mass of solute x 100 Total mass of solution Recall:
Section 15.2 Describing Solution Composition 1. To understand mass percent and how to calculate it Objective.
