So iodate, hydrogen peroxide, malonic acid
碘酸根离子，过氧化氢，丙二酸
in the presence of sulfuric acid
在硫酸存在的条件下
react to produce this compound
反应生成这种化合物
oxygen and water
氧气和水
But think about the reaction this way
不过像这样考虑反应
It's equivalent to saying that metal and plastic
无异于说金属和塑料反应
react to produce a bicycle
生成自行车
In reality, there are many steps
实际有很多步骤
that occur between those raw materials and the finished results
发生在原材料和最终产品之间
and the Briggs-Rauscher reaction is similar
Briggs-Rauscher反应也是这样
Here are the many subreactions that occur
这里需要有很多子反应发生
to get from the reactants
才能从反应物
to the products
得到产物
What we see is a cycle from colorless to amber to dark blue
我们所看到的是从无色到琥珀色到深蓝色的循环
And as these reactions run
随着这些反应的进行
the relative amounts of the reactants and the products
反应物和产物的相对浓度
dictate the color of the solution
决定了溶液的颜色
I2 is amber
I2是琥珀色的
I minus is colorless
I-是无色的
and I three minus is deep blue when it interacts with starch in the solution
而I3-在同淀粉溶液相互作用时是深蓝色的
triiodide is formed when
三碘阴离子能在
iodine and iodide interact
碘单质和碘离子相互作用时形成
And this cycle continues until all the reactants are used up
这个循环会一直持续，直到反应物被耗完为止
