Baking Powder Hypothesis

865 Words4 Pages

Will cookies bake the same if baking powder is used instead of baking soda? This is an interesting question because if baking powder can replace baking soda, it eliminates the need for both items. It also raises the question regarding if these two ingredients are different. If they are, what different effects will they have on cookies? The hypothesis for this experiment is, if baking powder is used instead of baking soda, then the cookies will not rise.
There are several new terms being used in this report. The word leaven means to cause bread or dough to rise. Sodium bicarbonate, another name for baking soda, is a soluble white powder used as a leavening agent in baking. Decomposition is a process in which a chemical compound is broken down into simpler matter. Leavening agents are substances that, through the release of gases, cause doughs and batters to rise. Alkaline means that a substance has the opposite effect of an acid. Baking soda is a white alkaline powder. It contains one ingredient, sodium bicarbonate, a base that reacts by releasing carbon dioxide in the form of bubbles when it comes in contact with acids, such as buttermilk, coffee, and brown sugar. Baking soda is made from sodium …show more content…

This made me reconsider my original hypothesis that if baking powder is used instead of baking soda, the cookies will not rise. My new hypothesis is that if baking powder is used instead of baking soda, the cookies will continue to rise for an extended period of time and therefore be thicker than the baking soda cookies. I do expect to encounter some problems with this experiment. One problem is that the cookies in each batch could be different sizes, so they would need to bake for different amounts of time. I will try to avoid this problem by using a measuring spoon to scoop out the cookie dough, so each cookie is the same

Alka Seltzer Research Paper

79 Words | 1 Pages

Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.

Alka-Seltzer Experiment

853 Words | 4 Pages

Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

Soda And Mentos Lab Report

My hypothesis was correct because Diet Pepsi has the least amount of soda left in the bottle of the explosion out of Coke, Root Beer, Fanta, and Soda water. According to the data table Diet Pepsi had the smallest amount of soda left in the bottle, it had 620 mL left. I think my hypothesis was correct because like stated in the hypothesis, Diet Pepsi contains potassium benzoate, aspartame, and the carbonation which react to mentos. Specifically, the tiny pores in the mentos which helps the geyser form. Though, the other sodas tested contained carbonation, potassium benzoate and aspartame, have a role in the reaction to the

I predict that the more baking powder added to the vinegar, the more reaction will take place causing for more gas to be produced per 10 seconds. There will be a gradual decrease in difference between volume in gas per 10 seconds over the duration of time. 
I predict that the more baking powder is added, the more gas will be produced because there is more vinegar to react with baking powder

Compare And Contrast Vinegar Vs Baking Soda

336 Words | 2 Pages

Everyone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings. When vinegar and baking soda are combined, the hydrogen ions in the vinegar interact with the sodium and bicarbonate in the baking soda.

Ionic And Covalent Compounds Lab Report

The wax melted first, followed by the salt, and lastly the sugar. The salt not only burned before the sugar, but developed a brown color throughout most of the substance at a faster pace. In the water solubility test, the salt dissolved in the water, as soon as it was properly mixed and the sugar dissolved in the water as well, but was stirred for a longer period of time until it was completely dissolved. The wax did not dissolve in the water, however bits of the substance broke off from the main piece. With this information, the final results included: wax as a nonpolar covalent compound, since the substance melted first and was not soluble in water; salt as a polar covalent compound, since the substance was soluble in water and the second to melt; and sugar as an ionic compound because the substance melted last and was soluble in

Bulk Fermentation Process

Which will make the dough to rise, and the alcohol produced mostly evaporates from the dough during the baking process. As fermentation occurs each yeast cell forms a centre around which carbon dioxide bubbles form. Each of the bubbles is surrounded by a thin film of gluten form cells inside the dough piece. When these cells fill with gas the dough is increased in size. During rising, if any large gas holes formed, they will be released by kneading.
