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

electrically charged atom or group of atoms formed by the loss or gain of one or more electrons. Ionization - The condition of being dissociated into ions by heat‚ electrical discharge‚ radiation‚ or chemical reaction. Electrolyte - A chemical compound that ionizes when dissolved or molten to produce an electrically conductive medium. Dissociation - When an ionic compound breaks up into its ions. The experiment started by placing the rods of the light bulb device into the beaker in which contained

Viscosity of sweetened water Avery Safley Introduction: Have you ever wondered why your honey comes out of the bottle so slow? The answer to this is viscosity. Viscosity is the resistance of a liquid to flow. Every liquid exhibits this resistance to some degree. Therefore the more resistance shown‚ the higher the viscosity. It can be thought of as fluid friction‚ just as solids show friction between other solids. This friction is caused by the molecules within the substance. Viscosity is

Viscosity Investigation Research Question: How does the concentration of C6H12O6 affect the viscosity of a C6H12O6 solution? Hypothesis I believe that as the C6H12O6 concentration increases‚ so will the viscosity of the solution. I think so because the increased number of electrons caused by the greater mass of C6H12O6 will lead to stronger Van-der-Waals forces. Furthermore I believe that because of the increase of C6H12O6 particles‚ indicated by the increased number of moles of C6H12O6‚ there

Viscosity of Liquids Part I: Low Viscosities Mona Kanj Harakeh 1 Objectives • To measure and analyze the viscosities of ideal (Toluene/p-Xylene) and nonideal (Methanol/Water) binary solutions and their components. • To determine the Activation Energy to viscous flow. • The effect of temperature change on the viscosity will be studied. Method: The viscosities of liquids are determined by measuring the flow time for various liquids in an Ostwald viscometer. 2 Ostwald viscometer 3

Alterations in Fluids‚ Electrolytes‚ and Acid-Base Balance Composition & Compartment Distribution of Body Fluids ← Body fluids are distributed between the intracellular fluid (ICF) and extracellular fluid (ECF) compartments. The ICF compartment consists of fluid contained within all of the billions of cells in the body. It is the larger of the two compartments‚ containing approximately two thirds of the body water in healthy adults. ← The remaining one third of body water is in

Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and the transcellular fluids such
