The blood plasma is consists of electrolytes. It comprise of both negative and positive charge. The negative charge is made up of chloride‚ bicarbonate and phosphates. The positive charge is made up of calcium‚ sodium‚ potassium and magnesium. This specifies the condition of the body’s acid-base ratio‚ water balance‚ endocrine and renal systems. These indicate the condition of your body’s acid-base ratio‚ endocrine and renal systems‚ water balance and other conditions. There is a fine line between

lab experiment was to examine the reaction between cations and anions‚ as well as observing‚ and documenting the chemical reactions. We will be demonstrating the reaction between a solution of Lead Nitrate with a chemical formula of PbNO3 2‚ and a Potassium Chromate solution with a chemical formula of K2CrO4. The end result from mixing the two solutions should have a combined set of either the Pb2+ or K+ cation and likewise with the NO3 2- or CrO4 2- anion in its chemical formula. This experiment will

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants with the mass of the products. I calculated the percent yield and the percent error for this experiment and I also compared the amount I produced at the end with the amount I expected to get‚ using stoichiometry. II. Materials: * 0.00500 moles of potassium chromate * 0.00500 moles of lead (II) nitrate

reactive than alkanes due to the presence of carbon-carbon bond. Objectives: * To know if potassium permanganate solution will show reactions with oil and fat samples. * To determine if the results of the performed experiment are saturated or unsaturated and alkane or alkene if the samples are mixed with potassium permanganate. Hypothesis: If the fats and oils will be added by potassium permanganate solution then we will know if it is an alkane or an alkene. Materials and Methods

is the wavelength at which the complex absorbs the most light; allowing the lowest amount to reach the sensor. The source of phosphate for making our standard curve was potassium hydrogen phosphate‚ and this wavelength allowed us to target and analyze only the phosphate-AVM complex while yielding the least impact from the potassium ions. As for the colas‚ they are made with so many ingredients that it was very important to have a good analytical wavelength. In addition to phosphate‚ there is caffeine

The control group would be potassium cyanide‚ a common inhibitor in which the others are being compared to. The treatment group would be not adding any inhibitors to the solution. Results The resulting effects of the inhibitors on photosynthesis and respiration are as such; for potassium cyanide on respiration and photosynthesis

Introduction In this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid.
