At its most elemental level, the art of cooking is about chemistry, namely how food components react with one another. Acids and bases are the foundation of these chemical reactions in food preparation. The ways that acids and bases work together can enhance flavor, tenderize seafood and meat, get baked goods to rise properly and even put out a kitchen fire.

An acid is a solution with a value between 1 and 6. A base is a substance with a pH value greater than 7. Bases are termed "alkaline," meaning that they neutralize acids.

Water, which has both acid and base, is considered chemically neutral, having a pH of 7. Acids make foods taste sour, and most foods fit for humans to eat tend to have more acid than base in their composition.

Natural sugars in the food counterbalance acids' sour flavors to make them taste better. Think of the difference between eating a slice of orange vs.

With much more natural fruit sugar, or fructose, the orange is much tastier than the lemon. Acids serve to soften, or "denature," foods that have lots of proteins. The fish appetizer known as ceviche is "cooked" in lime juice, an acid that breaks down proteins in the fish.

The lime juice's effect on the fish proteins gives the dish an appealing mouth texture and an opaque appearance that resembles cooking with heat. Tough cuts of meat often are soaked in marinades made with vinegar, lemon juice, tomato juice or other types of acids to tenderize them and add flavor. Marinades don't penetrate deeply into meat without piercing the flesh extensively, so the acid helps to open up the outer protein cells to accept the seasoning.

Cooking with bases is a little trickier, because alkaline substances react with fats in recipes to turn into soap, which is hardly a tasty result. Before modern food processing, indigenous peoples would "cook" maize, or corn, in the alkaline ashes from their cooking fires. The process softened the outer hulls of corn kernels, making them easier to digest and releasing important nutrients. Bases play an essential role in baking for their ability to react with acids and release carbon dioxide gas.

Baking soda is the most common base used in cooking. Gas bubbles form in batter or dough when baking soda combines with any acidic ingredients, such as yogurt, lemon juice or buttermilk. This process is known as leavening, a reaction that causes batter or dough to rise up.

However, baking soda can only cause so much lift unless there's a great deal of it in the recipe, which can result in a soapy taste to baked goods. That's why some recipes also call for baking powder, a product that combines baking soda with a powdered acid that reacts with water. Baking soda has one other advantage in the kitchen -- it's a natural fire extinguisher. Known chemically as sodium bicarbonate, baking soda breaks down at degrees Fahrenheit into sodium carbonate, carbon dioxide gas and water vapor.

This reaction will smother any kitchen fire that shouldn't be doused with water, such as flaming oil or grease. Nutrition Cooking and Baking Cooking Basics. Cynthia B.

In the Advanced Acids and Bases simulation, you will learn all about the characteristics of weak and strong acids and bases, which will not only help you get a better understanding of chemistry, but also let you help out the lake ranger, Victoria, in the process.

Victoria is bewildered by the condition of the lake she is monitoring, as all the animals living in the lake have suddenly disappeared. Your first mission in the Advanced Acids and Bases lab is therefore to take water samples of the lake and analyze their pH in the lab. The goal is to try to identify connections between the measured pH and the lake conditions. By applying the concept of neutralization, you can create different types of salt.

This will come in handy for solving real-life issues, such as environmental hazards. All our simulations run on laptop and desktop computers, and you can play our simulations without having to install any browser plugins.

Designed to be suitable for introductory courses or high school classes, the new Principles simulations cover the core principles of scientific concepts in biology, chemistry and physics to introduce students to the topics or provide a base level of understanding for non-majors.

Some of these simulations were created specifically for this new package, whereas others have been converted or combined from previous simulations which is why some of these titles may seem familiar to experienced Labster users!

Introductory Lab

The Principles simulations have been developed in a number of ways to be more level-appropriate without losing their academic rigor. To better explain difficult concepts, Principles simulations have adapted vocabulary in terms of the simulation flow and quiz questions, as well as modified or shortened content where necessary. These labs are also a mix of both concept- and technique-based so students get a better all-round understanding of the subjects they are learning.

Overall, there are 28 core Principles simulations — 14 of which are brand new — bringing the total to more than 60 simulations included in the overall Principles packages.
