科学探究是奇妙的过程,请你一起参与实验探究。【提出问题】有一天,小松同学用“双氧水”(过氧化氢溶液)清洗伤口时,不小心将过氧化氢溶液滴到水泥地板上,发现有大量气泡产生。小松联想到自己曾经用二氧化锰做过氧化氢分解的催化剂,他想,水泥块能否也可做过氧化氢分解的催化剂呢?于是他到附近建筑工地取回一些小水泥块,再用蒸馏水浸泡、冲洗、干燥,拿到学校和同学们一起进行了以下的探究。
Scientific inquiry is a fantastic process, please participate in the experimental inquiry together. [Ask a question] One day, Komatsu students with “hydrogen peroxide ” (hydrogen peroxide solution) to clean the wound, the accidental drops of hydrogen peroxide solution to the concrete floor and found a large number of bubbles. Komatsu thought he had used manganese dioxide as a hydrogen peroxide decomposition catalyst, he thought, cement blocks can also do hydrogen peroxide decomposition catalyst? So he went to a nearby construction site to retrieve some small pieces of cement, reuse Distilled water soaked, rinsed, dried, get the school and the students conducted the following inquiry together.
