Experiment 2 - Solubility of Inorganic Salts Beginning Questions 1. Which Cation/Anion Sources sterilize out dissociate in solution? 2. Is there a practice soluble and insoluble or is there an in betwixt? 3. Why be some ions more attracted to pissing molecules than to distributively other in solution than other ions? 4. What is the cut down of forming a precipitate? Safety Considerations Wear proper PPE: gloves, goggles, cover legs and feet. throw off of the solutions in a proper unsettled waste container and non in sink. Clean the well plate with body of urine onwards and after the experiment. Hazardous chemicals: Cu(NO3)2 and Ba(NO3)3 ar heavy metals and should not be disposed off in the city water system. action: 1) Washed and rinsed the well plate obtained from the laboratory tune room 2) twain drops of the anion source Na2SO4 were placed in the ennead wells of the start-off row of well plate 3) ogre drops of the anion source Na2CO3 were placed in the night club wells of the chump row of well plate 4) Two drops of each of the nine Cation sources were place in the original and second rows where the anion sources were placed anterior 5) The contents of all the cells were observed and recorded in the lab notebook using the five descriptions: Clear, Cloudy, Opaque, Colorless and Colored.
The recordings are draw in table 2.1 6) Two other groups beat as well recorded with 2 sets of anions and all the nine Cations. Their recordings are to a fault noted in the table 2.1 7) The procedure was repeat the first time using the selfsame(prenominal) Cation Sources but wi! th unalike anion sources salts. 8) The procedure was iterate the second time using the same Anion Sources from the first divide but with different Cation sources salts.
