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

was performed at Texas State University – San Marcos in the Chemistry lab. The concentrations used in the experiment were 0.5M of sodium hydroxide and 0.5M of sodium hypochlorite. The concentrations of the solutions found in the dumpster were calculated to be .806 M (both sodium hypochlorite and sodium thiosulfate as well). This was found by taking the 6.0% (by mass) sodium hypochlorite and multiplying it by 1 gram of solution‚ 1000 mL and 1 mol NaClO. This result was then divided by the result of 100g
