Which indicator would be the best to use for a titration between 0.30 M (CH3)2NH with 0.30 M HI? You will probably need to consult the appropriate table in the book.1.  alizarin yellow R, color change at pH 10-122.  methyl red, color change at pH 4-63.  bromothymol blue, color change at pH 6-84.  thymol blue, color change at pH 8-105.  phenol red, color change at pH 7-9
