been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although

(2008) suggests that when individuals/families seek counseling or therapy‚ they are more likely to encounter a therapist who practices “cognitive behavioral therapy‚ solution focused therapy‚ or Bowen family systems rather than a therapist whose primary orientation to treatment is collaborative language or second order cybernetics” (p. 290).

Abstract This laboratory involved utilizing equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data

identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative reaction with the indicator solutions. Seven sets of three
