Ch 3: GRE Biology: Inorganic Chemistry Review

About This Chapter

Take another look at key inorganic chemistry concepts, like chemical bonds and solution pH, with the video lessons and quizzes found in this test-prep chapter. Our experienced instructors can help you master these topics and more in time for your GRE Biology exam.

GRE Biology: Inorganic Chemistry Review - Chapter Summary

Brush up on chemical bonding, solution chemistry and chemical reaction basics to prepare for the GRE Biology exam. The entertaining video lessons included in this chapter can help you review the following topics:

  • Cellular molecules, macrominerals, and trace elements
  • Covalent, ionic, polar covalent, and hydrogen bonds
  • Properties of ice and liquid water
  • Solutions, solutes, and solvents
  • Saturation, osmosis, and diffusion
  • Acids, bases, and solution pH
  • Oxidation-reduction reactions
  • Hydrolysis and dehydration reactions
  • Anabolism and catabolism

The video lessons and transcripts found in this chapter are accessible through a modular course format that allows you to take on as many topics at a time as you'd like. There are also self-checking lesson quizzes and a chapter test useful for determining how much more study time you need to put in. Plus, our experienced instructors are available to answer any questions you might have about inorganic chemistry.

GRE Biology Objectives

GRE subject tests are used to gauge the academic preparedness of applicants to graduate degree programs. If biology is a subject area where you excel, you might consider submitting GRE Biology test scores to supplement your other application materials.

The test itself contains around 190 multiple-choice questions covering three main content domains. The videos and quizzes included in this chapter can help you review the inorganic chemistry concepts you'll need to successfully answer questions found in each of the exam's cellular and molecular biology, organismal biology, and ecology and evolution sections.

The Foundational Elements of Life

1. The Foundational Elements of Life

Living things are complex products of their environments. They are made of a number of different natural elements, many of which are essential to survival. Because of this, they are considered foundational elements and they support life on Earth as we know it.

Chemical Bonds I: Covalent

2. Chemical Bonds I: Covalent

Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.

Chemical Bonds II: Ionic

3. Chemical Bonds II: Ionic

Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.

Chemical Bonds III: Polar Covalent

4. Chemical Bonds III: Polar Covalent

Are you confused about how you can tell what kind of bond two atoms will form? This lesson will help you understand the difference between polar and nonpolar covalent bonds as well as how to predict how two atoms will interact.

Chemical Bonds IV: Hydrogen

5. Chemical Bonds IV: Hydrogen

This lesson defines and discusses important concepts behind hydrogen bonding. You'll learn when and why these bonds occur and which atoms are often involved.

Properties of Water

6. Properties of Water

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Solutions, Solutes, and Solvents

7. Solutions, Solutes, and Solvents

Solutions, solutes, and solvents are terms that are frequently thrown around in chemistry. Find out what these terms mean and learn why certain substances form solutions.

Osmosis, Diffusion and Saturation

8. Osmosis, Diffusion and Saturation

The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.

Acids and Bases

9. Acids and Bases

Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.

Basic Properties of Chemical Reactions

10. Basic Properties of Chemical Reactions

Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

11. Redox (Oxidation-Reduction) Reactions: Definitions and Examples

This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.

Hydrolysis and Dehydration: Definitions & Examples

12. Hydrolysis and Dehydration: Definitions & Examples

Water is an important component of cellular processes. Two of these processes, dehydration and hydrolysis, help your body build large molecules from small ones and break down large ones into usable components.

What Are Ionic Compounds? - Definition, Examples & Reactions

13. What Are Ionic Compounds? - Definition, Examples & Reactions

Ionic compounds are a common, yet special type of chemical compound. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions.

Anabolism and Catabolism: Definitions & Examples

14. Anabolism and Catabolism: Definitions & Examples

Metabolism breaks down large molecules like food into usable energy. This energy drives bodily processes critical to survival. In this video lesson, you will learn about the two forms of metabolism that break down and build up molecules and see examples of each.

Weak Acids, Weak Bases, and Buffers

15. Weak Acids, Weak Bases, and Buffers

This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.
