碘酸根離子,過氧化氫,丙二酸
So iodate, hydrogen peroxide, malonic acid
在硫酸存在的條件下
in the presence of sulfuric acid
反應生成這種化合物
react to produce this compound
氧氣和水
oxygen and water
不過像這樣考慮反應
But think about the reaction this way
無異于說金屬和塑料反應
It's equivalent to saying that metal and plastic
生成自行車
react to produce a bicycle
實際有很多步驟
In reality, there are many steps
發(fā)生在原材料和最終產(chǎn)品之間
that occur between those raw materials and the finished results
Briggs-Rauscher反應也是這樣
and the Briggs-Rauscher reaction is similar
這里需要有很多子反應發(fā)生
Here are the many subreactions that occur
才能從反應物
to get from the reactants
得到產(chǎn)物
to the products
我們所看到的是從無色到琥珀色到深藍色的循環(huán)
What we see is a cycle from colorless to amber to dark blue
隨著這些反應的進行
And as these reactions run
反應物和產(chǎn)物的相對濃度
the relative amounts of the reactants and the products
決定了溶液的顏色
dictate the color of the solution
I2是琥珀色的
I2 is amber
I-是無色的
I minus is colorless
而I3-在同淀粉溶液相互作用時是深藍色的
and I three minus is deep blue when it interacts with starch in the solution
三碘陰離子能在
triiodide is formed when
碘單質(zhì)和碘離子相互作用時形成
iodine and iodide interact
這個循環(huán)會一直持續(xù),直到反應物被耗完為止
And this cycle continues until all the reactants are used up
但愿大家喜歡這個視頻,下次再見
