    Toxicology Lab      1. In  this investigation‚ a wide range of concentrations of  Sodium Chloride (NaCl) solution  were   created   and  the  effects  that  they  had  on  radish   seeds  were  tested.  This  ultimately  created  a  dose­response  experiment  in  which  it  was  detectable whether  or  not  radish  seeds  were  a  reliable  bioassay  for  the   toxicity  of  NaCl.  The  goal  of  this  experiment  was  to  determine  a  correlation  between  toxicity  and  seed  germination/radicle

    Conclusion: The purpose of this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring

The watch glass was weighed in grams. 2 mLs of the sodium chloride solution was pipetted into a 10 mL graduated cylinder that would be transferred to the watch glass. After this transfer‚ the watch glass and sample were reweighed and recorded. To figure out the mass of the solution‚ the plain watch glass was subtracted from the plain watch glass plus solution. The watch glass was placed in the oven for approximately 20 minutes until the water evaporated‚ and

    • 4 Pages

    Mixtures and Solutions can often become confusing because solutions are mixtures‚ but not all mixtures are solutions. A mixture can either be homogeneous or heterogeneous. A homogeneous mixture is where the mixture’s components are distributed uniformly within the mixture. A heterogeneous mixture is where the components are not uniform. Mixtures can either be miscible or immiscible‚ the difference being whether or not the mixture forms a homogeneous mixture or not. In a solution a solute is soluble

    Abstract Through three different experiments we were to find the quality of NaCl as a deicer. These experiments included testing the freezing point depression of NaCl in solution at two different concentrations‚ testing for the H of an aqueous NaCl solution‚ and combining NaCl with MgCl2 in an aqueous solution to test for freezing point depression. Through these various experiments we found NaCl to be the best deicer for our region due to its proficient freezing point depression and its cost
