For a school project I'm trying to model the Oregonator and perform some experiments with the Belousov-Zhabotinsky reaction. Like predicting the reaction and the swings in concentrations. For that it is of course crucial that I perform the correct BZ-reaction, the reaction where the Oregonator is based on. 


In the paper ['An Analysis of the Belousov-Zhabotinskii Reaction' by Casey Gray](https://scholar.rose-hulman.edu/rhumj/vol3/iss1/1/) I found a mathematical analysis of the Oregonator. For the experiment at school I want to perform the experiment exactly as described in the images below (the images are from the same paper).


Now I have a problem, because there are many different recipes on the internet, all a bit different. I am no experienced scientist, so I have difficulty determining which recipe I should use. So my question is: what is the exact recipe I should use for the (below) BZ-reaction? Which concentrations, how much of them and in what order I should add them (and any additional things that I should do).


Second, are the ingredients used in the BZ-reaction common in most laboratories? I need to perform the experiment at school; what are the chances they have those ingredients? And if school does not have some of chemicals, are they expensive? 


Third, is ferroin the best (visual) indicator for the BZ-reaction? Is ferroin expensive (to make)? Are there alternatives that visually indicate the changes in concentrations?
