The limitations of measuring pH by colour indicators / B.C. Syrett and J.G. Garrison, Physical Metallurgy Division.: M34-20/117E-PDF
“Aqueous solutions containing various amounts of NaC1 and FeC12, were prepared and their pH's estimated using pH-indicators in three forms: indicator-impregnated filter paper, indicator-coated silica gel particles, and aqueous solutions of the indicators. It was found that silica gel was an unsuitable medium for carrying the indicator because of its own acidic nature, and that the proportion of indicator to test solution can influence the accuracy of the pH estimation. It was also found that the success of the indicator-paper method depends on the concentration of the indicating solution used in the preparation of the paper, and on the concentration of dissolved salts in the test solution"--Abstract, p. i.
