Who's it for?
This chapter of our college-level general chemistry tutoring solution will benefit any student who is trying to learn about solutions and earn better grades. This resource can help students including those who:
- Struggle with understanding the rate of dissolution or how to calculate molarity and molality concentration or use colligative properties to determine molar mass or any other solutions topic
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their solutions unit
- Cope with ADD or ADHD
- Want to get ahead in chemistry
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about solutions simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live chemistry tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn solutions on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Study the factors that affect the rate of dissolution.
- Learn how a solution is formed.
- Find out how to determine the solubility of a substance in water.
- Calculate dilution of solutions.
- Learn to use colligative properties to determine molar mass.
- Determine the main colligative properties.
1. The Rate of Dissolution: Factors and Definition
Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.
2. Solutions, Electrolytes and Nonelectrolytes
Learn what a solution is and how it is formed. Learn how to express the concentration of a solution in terms of molarity, molality and mass percent. Discover the differences between an electrolyte and a nonelectrolyte.
3. Solubility and Solubility Curves
Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.
4. Calculating Molarity and Molality Concentration
Learn the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.
5. Calculating Dilution of Solutions
Learn what a solution is and how to properly dilute a new solution from a stock solution. Learn the dilution equation that combines molarity, the volume of stock solution and desired solution to determine how much stock solution is needed for the new solution.
6. Using Colligative Properties to Determine Molar Mass
In this lesson, we will explore the effect of colligative properties on a solution. We will learn how to calculate freezing point depression and see how it can be used to calculate the molar mass of an unknown substance.
7. Colligative Properties and Raoult's Law
Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.
8. How Do Aqueous Solutions of Ionic & Molecular Compounds Differ?
Why does sodium chloride conduct an electric current when dissolved in water while sugar does not? In this lesson learn about how the type of bonding of atoms in a compound determines how the compound dissolves in water and how its aqueous solution properties are influenced.
