First, found the problem Sunday, Xiao Jie and her mother clean the kitchen, she found the stove around the tiles on the oil is not good to clean. They have to shovel thick grease with a small shovel, spray detergent, and then scrub with a clean ball. When she thought of the common alkali sodium hydroxide that she had just learned, she could react with the grease, so she wanted to verify that the use of sodium hydroxide in addition to greasy dirt effect. Second, the experimental verification Monday, Xiao Jie arrived at the school can not wait to find a chemistry teacher, his own degreasing process and would like to verify the addition of sodium hydroxide degreasing
