Dislike of science is now spreading over students and even teachers in Japanese elementary schools. It seems that interest in science (chemistry) may often be generated through experiments. Therefore, we started an automatic service in the homepage of our chemical laboratory on how to prepare aqueous solutions (calculating concentrations and preparation methods) hich are the bases of some chemical experiment, in order to reduce dislike of science and to do various experiments using solutions prepared by teachers in elementary schools. Even a person who has no background in computers can use it anytime when it is necessary. Furthermore, we started a download service, so you can carry out this program even in a PC (offline) if you download a compressed file and extract it. On previous reports, we discussed about sodium chloride aqueous solution, sodium hydroxide aqueous solution, hydrochloric acid, ammonia water, acetic acid aqueous solution, nitric acid aqueous solution, sulfuric acid aqueous solution, solubilities of solid anhydrates, carbon dioxide and lime water, oxalic acid aqueous solution, sodium oxalate aqueous solution, potassium chloride aqueous solution, ammonium chloride aqueous solution, sodium hydrogencarbonate aqueous solution, sodium carbonate aqueous solution, solubilities of alums and related substances, and already started service in the homepage. In this report, we have developed the program for the preparation of hydrogen peroxide aqueous solution and for the production of oxygen.
