    The Formula of Succinic Acid Succinic acid is a diprotic, which means it donates two protons per molecule. Succinic acid can be completely neutralised by sodium hydroxide. The indicator most suitable for this experiment is phenolphthalein, it is colourless in acids and pink in alkalises. The half way stage is about pH 9.3, this is when it will either change from colourless to a very pale pink or from pink to colourless. To determine the relative formula mass of succinic acid I am going to

    The Molecular Formula of Succinic Acid The relative formula mass is the mass of 1 molecule of succinic acid compared with 1/12th of the mass of an atom of carbon-12. This is obtained by adding together the relative atomic masses of the atoms within the molecule according to its written formula. However we do not know the exact formula: HOOC(CH )nCOOH Where n is a whole number between 1 and 4 So to calculate the relative formula mass I must use the formula m = n ×Mr

    Analysing the Ethanoic Acid Concentration in Different Types of Vinegars Vinegar is a mixture of various acids, ethanoic acid being the most abundant. Most vinegars are made from a sugary liquid, this liquid is fermented to produce ethanol and then oxidised to form ethanoic acid. Different vinegars use different sugary liquids and this could lead to variation between the vinegars. My aim in this investigation is to discover whether the concentration of ethanoic acid varies between vinegars

    The acidity or alkalinity level is dictated by the pH, potential of hydrogen, scale. Soil pH or soil reaction is an implication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is characterized as the negative logarithm of the hydrogen particle fixation. As the measure of hydrogen particles in the soil builds the soil pH diminishes along these lines getting to be more acidic. From pH 7 to 0 the soil is progressively more acidic and from pH 7 to 14 the soil is progressively

    occurs in the absence of oxygen molecules also known as an anabolic reaction. It is a process of glycolysis in which sugar molecules are used to create ATP. Fermentation has many forms the two most known examples are lactic acid and alcoholic fermentation (Cressy). Lactic acid fermentation is used in many ranges from food production such as bacteria to its use by fatigued muscles in complex organisms (Cressy). When experimenting with organisms such as yeast which was done in this experiment you follow

    plants and other living things, but one of the major ones is acid rain.The research the experimenter did was to aid in testing to see whether or not the pH level of water is an important factor in the growth of a radish plant.The experimenter believes that soil with a neutral pH of 7 will grow the most due to the fact that something with a natural pH of seven is neither acidic nor basic. Acid Rain Pollution in the air is the cause for acid rain.Factories, power plants ,and cars burn fuels which results
