Chem 108 Writing assignment # 1 Name_____________________________________ Use of detergents to remove Grease from Utensils After having a meal full of fat, such as pork, in the evening, I normally put the utensils in the sink, block it and then add water and detergent. The aim is normally to let the utensils in the sink overnight exposed to the detergent. The action helps to remove the grease from them and, thus, increase upon the chances of cleaning them effectively and easily in the morning. The molecules of detergent have two ends; these include the head and the tail. The head is hydrophilic and, thus, attaches itself to the water molecules. The tail of the molecules of detergents, on the other hand, is hydrophobic. It, therefore, attaches itself to the grease contained within the utensils. Thus, it aids in the ease of the removal of grease from the utensils easily. The practice is a normal exercise that may be applied by people to increase the ease of cleaning utensils, instead of spending a lot of time trying to scrape grease off them. Use of vinegar and baking soda to clean washing machine I normally use a mixture of vinegar and baking soda to clean the inner metallic surfaces of the washing machine. The two compounds react to form a solution that easily reacts with the dirt stuck on the surfaces of the washing machine. Thus, the dirt floats on top as residue, making it easy to be rubbed off by the use of a soft material such a piece of cloth. The action normally becomes possible as the dirt reacts with the solution formed from a mixture of the two. Thus, they reduce the level of adhesive force that exists between the dirt and inner surfaces of the washing machine. The use of the method to clean the inner surfaces of a washing machine is imperative, owing to the ease of availability of the material and the little effort that one requires to do the cleaning.
