Lactated Ringer’s Solution Lactated Ringer’s classified as an isotonic or crystalloid solution‚ has similar osmolarity to body fluids‚ meaning that it maintains fluid volumes in balance between the space inside and outside the blood vessels. Lactated Ringer’s contains electrolytes‚ substances necessary for cells to function. It’s intended for intravenous administration‚ but if a suitable vein cannot be found it can be given orally which has an unpleasant taste. It is made up of NaCl (sodium chloride)

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

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
