White crystal like substance and slightly thick White and fluffy with a relatively fluid motion Consistency after 1 hour Gelatinous with clear yellow liquid below Yellow mass, very thick not easily moved White crystal suspended in clear solution, somewhat fluid White mass in clear solution- looks fluffy and easily movable The last stage of the experiment was testing the soaps’ pH and cleaning properties. Using distilled water, tap water, and calcium chloride I was able to observe changes in the different oils. Observations in the amount of suds and any precipitates formed are recorded in Data Table 3, Testing the Soaps Cleaning Ability and pH. Data Table 3: Testing the Soaps Cleaning Ability and pH Canola Oil soap Corn Oil soap Coconut Oil soap Olive Oil soap Detergent 1.Distilled water: amount of suds? Very few- May have been a result of shaking Yes- There were many suds A few bubbles were formed at top Yes- About ¼ of the test tube was suds Yes- equal amounts of water and suds 2.Distilled water: precipitate? None present None present None present None present Kind of- Could be detergent 3.pH 10 8 12 12 10 4.CaCl2 added: amount of suds? None None None None Yes Suds became apparent 5.CaCl2 added: precipitate? None A little could be seen formed at bottom Solid formed looks like dirt Small amount of solid forming None
6.Tap water: amount of suds? None Yes equal to water level None Yes medium amount Approx. equal to the water 7.Tap water: precipitate? None Small particles Slight particles of solid None Un-dissolved detergent Calculations and Error- In this lab there were no calculations to do. The only possible sources of error occurred during the different phases of the procedure. In the first phase upon the addition of sodium hydroxide and the stirring the oils began to cloud up and also their firmness changed. Had I not mixed the two solutions evenly throughout I may not have been able to properly identify and rank the firmness. For example, if I had only stirred and not properly mixed in a vertical fashion it would have kept them separate and possibly unidentifiable in the firmness. In the second phase the water temperature would have to be at a hot and steady enough heat to help the oil and soap separate. The water did come up to a boil and then remained off of the heat afterwards, however, depending on the heat may not have been hot enough or too hot to help set the soaps. Finally, the analysis of pH and cleaning ability was done by shaking the tubes for a couple seconds upon the addition of different mediums.
