Laboratory Report December 6‚ 2010 Title: Combining Vinegar and Baking Soda Statement of Problem: We wanted to observe what kind of reaction would take place when combining white vinegar and sodium bicarbonate (baking soda). Equipment or Apparatus: Sodium Bicarbonate (baking soda)‚ white vinegar‚ 13 oz. vessel‚ cork‚ household measuring devices (for lack of a scale) such as glass measuring cup and metal measuring spoons‚ and safety goggles. Procedure: We selected a vessel and a cork

the temperature of the chemical reaction and by that time it was clear what it was. The students think that it is Citric Acid and Baking Soda. They think it is that because when you look at the physical properties of Baking Soda you can see that has clumpy and had some big pieces which would be like the clumps in the Mystery Mixture. Another thing that Baking Soda has is that it is powdery and when you turned it their was some always sticking to the side which would be like the stuff that stuck

bath salts‚ various fragrances‚ and other components. That said‚ there are a few key ingredients that most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below

3 Ways to Clean Your Toilet with Baking Soda Cleaning the toilet is probably the most irritating and tiring thing to do. The toilet is undoubtedly the filthiest part of our homes. You get fed up with scrubbing for hours and‚ in the end‚ you still feel that it isn’t clean enough. You experiment with many cleaning supplies but‚ none of them seem to work. Fortunately‚ we have the perfect solution to this problem. You can clean your toilet without wasting any time‚ money or energy. All you need are

Speed of Decomposition and Its Factors Purpose The term decomposition is the process of breaking down dead organisms to reuse them. Decomposition allows nutrients in organisms to become free after they die or have become old and they are ready to be used by living plants and animals for their growth. Without decomposition useful nutrients would remain locked inside of a dead organism and it would be very difficult for new life to grow. Most of the nutrients that are essential for the plants

Baking. I have always enjoyed cooking and baking. My parents worked a lot of hours when I was a teenager‚ so dinner was left to me to cook. I soon learned all the usual family classics like spaghetti bolognaise‚ shepherds pie‚ roasts and cooked breakfasts. I became a lot more adventurous when I had my own family and quite often get the recipe books out to try something new. I only really got into baking once our boys came along and wanted to make them homemade cakes for their birthdays. I remember

History of Baking The History of Baking First Baking Course Ever Find Some Grain‚ a Mortar‚ and a Pestle Way back in the year 8‚000 B.C.‚ some clever dudes in Egypt started crushing grain with a mortar and pestle. You can bet they were surprised when after a few twists and grinds‚ a German chocolate cake appeared. Just kidding. They only managed to make a rudimentary form of unleavened bread sort of like a Mexican tortilla--but it was still a pretty big accomplishment. They shared this information

Devon Backstrom February 5st 2013 PSU Chemistry 222 – Lab 4 Decomposition of Hydrogen Peroxide Abstract: This lab was designed to observe the decomposition of hydrogen peroxide into it oxygen and water. The equation for this reaction is H202 H2O + +1/2O2 thus by measuring volume and pressure of O2 generated the amount of O2 generated can be calculated which in turn can be utilized to determine the concentration of water already in the H2O2 solution. The results determined that 3.02% of the

Aim: To investigate the rate of thermal decomposition of CaCO3 at different temperatures. Research Question How does temperature influence the rate of thermal decomposition in CaCO3? Hypothesis Every time more heat is added to the element‚ CaCO3‚ thermal decomposition will take place faster because the heat is a catalyst which speeds up the reaction. Variables Dependent Variables → Mass of Calcium Carbonate Independent Variables → Temperature Controlled Variables → Calcium Carbonate

The actual rate of a chemical reaction however is dependent on two things; the temperature the actual experiment is performed at‚ and the concentration pertaining to the reactants. The rate of a reaction more often
