Abstract: The experiment was done to demonstrate the effect of ADH on the volume and concentration of urine in order to demonstrate the control of ADH over blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all

Materials and Apparatus The chemical used in the experiment are as follows: HCl‚ sodium ions‚ ammonium carbonate‚ barium nitrate‚ acetic acid‚ potassium chromate‚ ammonium hydroxide and potassium oxalate. The apparatus used include spot plates/watch glass‚ nichrome wire‚ alcohol lamp‚ salt‚ water and stirring rod. B. Procedure We obtain a few crystals then each of the salts from the counter‚ and we place separately

How does the heat released during the reaction between distilled water and Group 1 elements (lithium‚ sodium and potassium) vary as one goes down the group? OBJECTIVE The objective of the experiment is to measure the heat change during the reactions with minimal heat loss to the surroundings. MATERIALS The materials to be used in this experiment are: • Lithium‚ sodium‚ and potassium metal are the three Group 1 elements and reactants. • Distilled water is a reactant. • 250ml beaker to measure

use to maintain voltages across their cell membranes and to carry electrical impulses such as nerve impulses and muscle contractions across themselves and to other cells. The major electrolytes that are in our body are as follows: sodium (Na+)‚ potassium (K+)‚ chloride (Cl-)‚ calcium (Ca2+)‚ magnesium (Mg2+)‚ bicarbonate (HCO3-)‚ phosphate (PO42-)‚ sulfate (SO42-). Sodium is an abundant metallic element which is an important mineral for all living organisms. It is also widely used industrially

more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside): 4 mEq/L Potassium ( inside): 140 mEq/L The ratios of these two respective ions from the inside to the outside are: Na+ (inside)/ Na+ ( outside) =0.1 K+ (inside)/ K+( outside) = 35
