Jean Lab Conclusion

In this lab we asked the question, What concentration of bleach is best to fade the color out of the new denim material in 10 minutes without visible damage to the fabric? My group found out that 50% concentration of bleach is the best to wash out the color of the denim square. When the 50% bleach was tested its color removal was not as significant as the solution with 100% bleach, but averaged a 3.5 on a scale of 1-10. Taking a look at fabric damage for the 50% bleach solution, the average came up to be 1 on the scale. When we tested the 100% bleach, the color removals averaged to be a 8, but the denim damage was a 2, which was higher than the solution with 50%.  other sentence

While our hypothesis was supported our data,... that the 50% bleach solution was the best, there could have been errors due to having a slight delay in time. The fact that we had a slight delay in time was because we started with the wrong procedure. After we figured out that we had started the with the wrong procedure, my team and I cleaned up and started new. Two of my lab partners went and got clean materials (i.e. jean squares, petri dishes), and my other one and I filled up the beakers with the correct amount of bleach and water.

The lab was done to demonstrate how solutions with bleach and/or water can effect a piece of denim by the amount of color it washes and how much damage creates. By taking part in this lab I learned that both bleach is a very strong chemical and can get out stains and make denim white but it is also very damaging. Based on my experience from this lab i could apply this to real life situations, keeping in mind how strong of a chemical bleach is and how it can damage my clothes.
