experiment is to study the effect of citric and buffered lactic acids on the flavour of hard-boiled sweets and the effect of acids on various flavours in high temperature applications. Introduction Materials and Methods An amount of water‚ sugar and glucose syrup of 30g‚ 100g and 70g were weighed respectively into a stainless steel pot. The mixture was then heated and removed immediately from the induction cooker after reaching the desired temperature of 145˚C. Flavours of 0.51g and acid of 1.20g was added

Advantages: Sulfamic acid is the fastest de-scaler - It dissociates into hydroxonium ions more readily in aqueous solution than the others‚ therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers

Is there really such a thing as rain with acid in it? Yes‚ acid rain is a very real phenomenon worldwide‚ and it’s been documented since the 1800s‚ as the Industrial Revolution caused the burning of fossil fuels like coal‚ gas and oil. When these fuels or any other organic material like wood or paper are burned‚ they release compounds like sulfur dioxide (SO2) and nitrous oxides (NOx) into the air. Are SO2 and NOx the causes of acid rain? Indirectly‚ yes. When SO2 and NOx enter the atmosphere

Formic acid is known to be the simplest carboxylic acid‚ and it is an important factor in chemical synthesis and occurs naturally. The chemical formula for Formic Acid is CH202‚ and is mostly found in the venom of bee and ant stings. Formic acid is clear and colorless with a pungent odor. Formic acid is used in many ways; Formic acid is used to preserve livestock. It is also sprayed on animal food and fresh hay to reduce the decay rate. It can also be used as a pesticide to protect bee

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective it is‚

Lauric Acid Lauric acid‚ also known as Dodecanoic Acid‚ was discovered in 1849 by Marrsson T. It was first discovered in Lauraceae seeds‚ but it is also commonly found in soaps‚ vegetable oil‚ coconut oil‚ and breast milk. Lauric Acid is a clear‚ solid compound that is insoluble in water. It also comes in the form of a white powdery substance. The chemical formula is C12H24O2. It has a molecular weight of 200.32 g/mol. Lauric Acid also has a melting point of 44 C and a boiling point of 289.9

Acid rain is considered precipitation in the form of rain‚ snow‚ or fog. It is not regular precipitation. It is precipitation that is polluted by acid. Emissions of sulfur dioxide and nitrogen oxide into the atmosphere cause this precipitation to become acidic. These emissions are released into the atmosphere by human activity‚ such as automobiles‚ industries‚ and electrical power plants that burn fossil fuels like coal and oil. When these gases are released‚ they mix with water vapor in the clouds

this unknown sample. First‚ the plate was analyzed for its hemolysis characteristics. Afterwards‚ a Gram stain was performed from a sample of the agar plate and the slide was viewed under the microscope. Once‚ the microscopic visual was captured‚ a catalase test followed. Next‚ for further data‚ MSA results were recorded‚ along with antibiotic observations of demo plates. Lastly‚ with the information gathered‚ it was identified that the unknown sample was Streptococcus salivarius. Introduction:

Acid Rain and the Effects of our Monuments and Churches The two controlled experiments that I chose to do‚ do not involve trees or plants‚ which I think a lot of people will be doing. I wanted to explore the devastation that acid rain does to our historic monuments and beautiful churches. My first controlled experiment is based on the Statue of Liberty. It is made of copper so I am using pennies in my experiment. (nps.gov. n.d.) My observation is that acid rain corrodes metals
