Materials and Methods.
For the Solution and Dilution lab, 2 sets of materials were required. For the first set, when
determining dilutions, a 100 mL beaker, a 25 mL graduated cylinder, 0.025 L H2O, and 0.05g of
HCl were needed. For the second set, when determining solutions, the materials required
consisted of vinegar, baking soda mixed with DI water, tap water, 2.5M of HCl, 1M NaOH, litmus
paper, pH paper, universal indicator, and a glass sphere.
To begin, starting with the first of the two experiments in which dilutions were determined,
calculations were completed from a table provided by the instructor to determine the unknown
dilutions. It was also determined that a 100 mL beaker was best suited for the making dilutions,
and a 25 mL graduated cylinder for measuring out H2O and HCl. Through calculations, 0.025 L
of H2O were discovered to be needed, along with 0.05 g of HCl. The water was added to the
beaker first, followed by the HCl and observations were noted.
For the second experiment, each chemical or compound was placed in a glass sphere and was
tested for acidity and observation's using litmus paper and pH paper. This was repeated for
each corresponding chemical.
