... At pH 1.7 (= pK1), there will be a 1:1 mixture of the yellow and red species, which appears orange. As a crude rule of thumb, we can say that the solution will appear red when [Y−]/[R] ≲ 1/10, and yellow when [Y−]/[R] ≳ 10/1. The pH range (1.2 to 2.8) over which the colour changes is called the tran ...
