| Various pH indicators such as Cresol Red, c naphtholphthalein, Tropaeolin OOO, Thymol blue, and phenolphthalein can be used. |
| So instead of phenol, other coal tar products such as cresol, naphthol or benzene itself may be used. |
| Police said the poison used in the latest attack was cresol, a powerful and toxic disinfectant. |
| For this purpose a 0.5 per cent solution of the compound solution of cresol or of Lugol's solution has been found satisfactory. |
| Compound solution of cresol is an excellent remedy at this stage. |
| Cresol and phenol, found in Chloraseptic, may cause a brown or yellow-green color that darkens on standing. |
