The main purpose of this experiment is to determine the concentration of phosphate in a water sample by spectrophotometric analysis. Another objective of the experiment is to practice calculating and performing dilutions of solutions and to construct and utilize a calibration curve. Materials/Equipment Spectrophotometer 25-mL volumetric flask 1-mL, 5-mL, 10-mL, and 25-mL pipettes Pipette bulb Conductivity apparatus 100-mL beakers Cuvette Chemicals Used Phosphate Stock solution () Ammonium vanadomolybdate solution Various water samples of unknown Phosphate concentration De-ionized Water Procedure
