Has anyone had problems with EDTA turning a clear yellow solution? I used the same protocol that others in the lab used: 186.1 g of EDTA, add 500 ml of distilled water, then add NaOH pellets until a pH of 8 is reached...but it still turns out yellow. Does anyone know how to solve the problem? Thanks.
