tavia Posted January 17, 2006 Share Posted January 17, 2006 When you spill some acid on paper, why does it turn yellow? Link to comment Share on other sites More sharing options...
Borek Posted January 17, 2006 Share Posted January 17, 2006 Whether it does or not, depends on the paper and acid, so this question can't be answered. If you pour concentrated sulfuric acid on paper it will dehydrate cellulose, leaving mostly carbon, thus it will be black or brown.

akcapr Posted January 17, 2006 Share Posted January 17, 2006 pretty sure not all acids due that, specify what acids did that for you. Link to comment Share on other sites More sharing options...
JustStuit Posted January 18, 2006 Share Posted January 18, 2006 In chemistry we did this one lab where we added different acids to different paper samples and they turned different colors. It was kinda dull. Link to comment Share on other sites More sharing options...
akcapr Posted January 18, 2006 Share Posted January 18, 2006 maybe the paper was like soaked in different indicators then dried. Link to comment Share on other sites More sharing options...
