I was standardizing a solution of EDTA by titrations with a solution of zinc ion, and having fun with exposure settings on the G9.
The solution is yellow due to the presence of an indicator called xylenol orange. Once the zinc ion solution being added is done reacting with the EDTA in the flask, the solution will change from yellow to red.
