怎樣證明丙烷中含有碳?

可以燃燒丙烷
之後會釋出水同二氧化碳
可以用氫氧化鈣既飽和溶液即石灰水測試
會見到石灰水變得混濁
由於二氧化碳含有碳
所以就可以證明到丙烷有碳^^

burn it in oxygen(not air!).
Carbon dioxide will be produced.This gas can turn limewater milky but cannot turn acidified potassium dichromate from orange to green.Showing the gas produced is not sulphur dioxide.
