Here's a nice site that talks plainly about acid and how litmus is used: http://www.purchon.com/chemistry/acids.htm The colors of universal indicator are on the interactive chart at the bottom of the page. This other site tells you more than you ever wanted to know about methyl orange: http://antoine.frostburg.edu/chem/senese/101/acidbase/faq/methyl-orange.shtml
Good luck on your test.
