A few days ago, you shared the physical simulation software, which, at the request of a large number of fans, required chemical simulation software, so it took us a while to find it。
Let's take a look at the entire chemical simulation software. Noodles
The left side of the software is a laboratory device that is common in chemistry, such as straws, measuring cups, thermometers, alcohol lamps, funnels, platinum, etc。
With these common experimental devices, we can simulate the first half of junior high school, most of the experiments in high school textbooks。
Simulation laboratories to extract oxygen
There are three ways of producing oxygen in the laboratory, and i'm here to simulate it by software, either by heating potassium permanganate or by heating potassium chlorate and manganese dioxide。
First, a new experiment is being carried out, and then in the left toolbar an iron table, an alcohol lamp, a test tube, a catheter, a sink and a gas cylinder are found, respectively, on the right, as shown in the figure below, and are then connected by a catheter。
The mouse then clicks on the test tube, and the right key selects the properties, adding potassium chlorate and manganese dioxide。
This has essentially resulted in the development of an experimental scenario for the recovery of oxygen from potassium heated chlorate and manganese dioxide by software, followed by the direct combustion of alcohol lamps to collect oxygen, as shown in the figure below. Oxygen bubbles were created in the cylinders, so we collected oxygen into the cylinders by draining it。
Likewise, we can also produce oxygen by heating potassium permanganate, by venting, by experimenting with the environment and by operating like the above steps。
Simulation laboratory alkali indicator colouring
As shown in the figure below, both colour changes and red changes can be observed in the diluted sulphate (hcl), nitrate (hn03) and diluted sulphate (h2so4) solutions。
Hydrochloride, nitrate, sulphuric acid
For example, the colour of prism solution solutions dropped into solutions such as sodium hydroxide (naoh) and potassium hydroxide (koh) can be observed to turn blue。
It is also observed, for example, that the color of phenol phenol solutions is reded by dripping into solutions such as sodium hydroxide (naoh), potassium hydroxide (koh)。
Summary
Using software to simulate chemical experiments in chemical textbooks, we can achieve a real experimental effect by modelling real operations, including concrete steps to do an experiment。
The advantage of software simulations is to save large amounts of experimental material to prevent environmental pollution. The entire experimental process can also be recorded in video or animation, where students are shown in the classroom in the form of a ppt to improve their understanding。
There are also shortcomings in that children do not do it themselves and do not understand the phenomenon of experimentation in a profound way. So it's better for a child with an experimental condition to do it himself。
Therefore, software is suitable only for supporting children or for strengthening after school。
