Dishwashing Liquid History of Dishwashing Liquid * Soap was used for cleaning until 1916‚ when there was a shortage of fats needed to produce it during World War I. Because there was still a need for a cleaning product‚ synthetic versions were invented‚ which are now known as detergents. There was also a movement towards using detergents because there was a need for a cleaning agent that did not leave behind a residue as soap did‚ especially on fabric. Upon their appearance‚ detergents became common

(table salt) - 5.0 grams of baking soda (sodium hydrogen carbonate) - 5.0 mL of shampoo or liquid laundry detergent What buffer solutions are used for: This buffer solution is used in this lab for several reasons. First of all‚ the saltiness and acidity (pH) of the solution is very close to that in living things; as a result‚ the DNA will like to dissolve into this solution. Secondly‚ the detergent is added to help break down cell walls in the onion cells. Cell walls in living things are

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides

compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction Detergents and soaps are used for cleaning because pure water can

That is why the DNA “stuck” to the glass rod. d) The DNA we extracted was very gooey‚ and a sort of thick liquid. The DNA did appear flexible and that is because it is so small. The rigid double helix structure does apply but is too small to see. When we look at it from the naked eye it appears to be flexible. This is because of the hydrogen bonds in the nucleotides
