we used 7 different solutions to determine if it’s either base‚ acid‚ and neutral. These are ammonia‚ vinegar; drain cleaner‚ soft drink‚ baking soda‚ detergent‚ and lemon juice are the solutions that are going to be tested in this lab. My hypothesis for these solutions is ammonia is acid‚ vinegar is neutral‚ drain cleaner is base‚ soft drink is base‚ baking soda is base‚ detergent is base‚ and lemon juice is an acid. For the red cabbage it would be the same as using red and blue litmus. If the pH

To investigate the results of the different amounts of sodium bicarbonate (2g‚4‚8g)‚when put in the baking process to produce cupcakes‚obtained by the change of height of a cupcake measured by a ruler‚when baked at 180 degrees celsius for 20 minutes when measured with a ruler. Research question: What will be the result of adding different amounts sodium bicarbonate (2g‚4g‚8g) in a standard (vanilla) cupcake ‚when they are baked at 180 degrees celsius over a period of 20 minutes using an oven thermometer

vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic. Vinegar used in cooking and as a condiment begins to fizz when mixed with baking soda. Hydrogen peroxide usually used as a disinfectant reacts to iodine solution and starts to bubble. Oil is used to keep food from sticking to non food surfaces and

Objective: The main objective is to demonstrate the law of Conservation of Mass. Use Vinegar and baking soda to demonstrate the law of Conservation of Mass. Introduction: The law of Conservation of Mass states that mass is neither created nor destroyed during ordinary chemical reactions or physical changes‚ which means that no matter how dramatic of a change that a substance goes through‚ it will not lose mass. It may seem like it lost mass‚ and usually‚ if you weighed the result‚ it will have

Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited reactants. It is hypothesized that the limited reactant of this experiment is the baking soda. Materials- * 2

For the firsts three sets of titration trials of baking soda powder was used. About 0.3 grams of baking soda powder were measured and mixed with 20mL of deionized water in a beaker. Three drops of the indicator bromothymol blue were put in the baking soda solution and mixed well. A burette and funnel were rinsed off using water and cleaned well. The burette and funnel were rinsed a second time using

Chocolate Chip Cookies: A highly scientific chemical reaction of butter‚ sugar‚ eggs‚ vanilla‚ flour‚ baking soda‚ salt‚ and‚ of course‚ chocolate chips. The buttery‚ toffee notes of a perfect CCC is often considered the epitome of home baking‚ a simple yet reminiscing experience‚ taking many down a trip on memory lane. However‚ the classic chocolate chip recipe isn’t as “cookie cutter” as the back of the Nestle Morsel bag has you believe; there is actually a plethora of chemical reactions that take
