Procedure

Indicator compositions were prepared as for Example 11. The colorants used are listed in Table 13. The second solution (Indicator Composition 13) was prepared by adding 1.0 g of cobalt(II) acetate tetrahydrate {Co(C2H3O2)2.4H2O} (available from Sigma-Aldrich Fine Chemicals, St. Louis, Mo.) to 13 ml of water. Devices were prepared and tested as described in Example 11. The results are recorded in Table 13.
