    Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In

    The type of acid was clearly controlled in the method. It clearly states that hydrochloric acid is representing the digestive chemical whilst the antacid tablets represent the food being digested. It is evident that the hydrochloric acid was the acid used in all aspects of this experiment successfully controlling this variable. It is not certain whether the amount of acid was controlled throughout the experiment. This is because the amount of acid was not clearly outlined neither

    Mejia Chem 101 Section ADF Lab 4: Weak Acid Unknown Procedure: When testing the acid‚ use only between 0.2 g and 0.3 g for each trial (get as precise a measurement as you can). The general procedure is to weigh out your acid‚ dissolve it in water‚ add a couple drops of the indicator (phenolphthalein)‚ and then add the sodium hydroxide until you note a color change (from clear to pink). When the color change occurs‚ you have added enough base to completely react with the acid (the endpoint). You are

    Ashley Spees CHM 261- Batzer Chem Final Write Up- Kool Aid Lab Total Acid This part of the lab requires titration of Kool Aid with an NaOH solution. The reason titrations are used is to determine the concentration of an unknown solution by reacting a strong acid with a strong base. Titrations are hard to accomplish‚ though‚ due to the fact that indicators used to show the endpoints are very sensitive and one drop could make the solution titrate past its endpoint. Blue stock solution: 3 mg/L

    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. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas

    In order to find the Vitamin C content you will need to use a process called titration which‚ according to the Columbia Electronic Encyclopedia‚ is when you add a chemicals to a liquid in order to create a reaction which can determine the content of a substance inside the liquid. This is how you will find the Vitamin C content of different juices. Iodine will be added to the juice‚ which will create a reaction that can help determine the Vitamin C content. To start‚ pour 30 milliliters (mL) of Lugol’s

    with a known concentration of 4.047x10-3 M was obtained. A 250-mL sample of a 10-fold dilution of this ionic iron solution and 5 drops of concentrated HNO3 was made. This solution served as the source of ionic Iron for the remainder of the lab and was labeled “stock ionic Iron solution.” Next‚ a 50-mL aqueous ionic Iron and FerroZine® complex solution was prepared by adding 5.00mL stock ionic Iron‚ 3-mL of acetic acid buffer‚ 2-mL of 5% hydroxylamine hydrochloride‚ allowing five minutes for hydroxylamine
