hmm....a good question...this question striked me when(i don't know maybe month ago) mah bio teacher(bharat trivedi) asked us what makes u cr while cutting onions?okay..i had no idea..neither mah frnds had..bt he told me that onion contains some sulphur content in it..when it comes in contact with our eyes..it makes a very dilute sulphuric acid..nd thus our eyes get irritated...
now searching on the internet for getting deeper into dis..i got to knw that while u cut an onion..it releases a gas called Propanethiol S-oxide(wow!!). now this gas..gets mixed wid other enzymes to release sulphur gases..and gets into our eyes to create dilute sulphuric acid...ND WE CRY!!!!QUITE AMAZING!!!
