mordant black 2 is used as an indicator in comleometric titrations, usuall against Di Na EDTA Solution. the indicator is mixed with NaCl/ KI in appropriate quantity...
The indicator used in the EDTA method is typically Eriochrome Black T, or its chelates. This indicator changes color in the presence of metal ions, helping to determine the endpoint of the complexometric titration involving EDTA and metal ions.
Erio Chrome Black-T, is usually used as indicator. It is commonly known as EBT. EBT can easily form weak complex ,which can be replaced easily by Sequencing agent Ethylene Diammine Tetra Acetic acid
Eriochrome Black T is a common indicator used in EDTA titrations, not Echnrome Blue Black T. Eriochrome Black T changes color from blue to magenta when it binds to the metal ions being titrated with EDTA, indicating the endpoint of the titration.
Hydroxylamine hydrochloride is added in the preparation of Eriochrome Black T indicator to reduce the dye to its colored form. This reduction step is essential to activate the indicator dye and make it suitable for use in complexometric titrations, where it will form a colored complex with metal ions.
Starch solution is used in the Winkler method to act as an indicator for the presence of oxygen. When titrating the sample with iodine, the starch solution forms a blue-black complex with the iodine in the presence of oxygen, providing a visual endpoint for the titration. This helps to accurately determine the amount of dissolved oxygen in the sample.

Mordant black indicators are used in complexometric titrations to visually signal the endpoint of the titration. They form colored complexes with metal ions, resulting in a visible color change when all the metal ions have reacted with the titrant. This color change helps in determining the endpoint of the titration accurately.
The indicator used in the EDTA method is typically Eriochrome Black T, or its chelates. This indicator changes color in the presence of metal ions, helping to determine the endpoint of the complexometric titration involving EDTA and metal ions.

Iodine is an indicator for starch. It turns blue-black in the presence of starch, making it a useful tool for detecting the presence of starchy substances in solutions or biological samples.
Iodine is used to indicate whether starch is present in a solution. If starch IS present, the indicator will turn dark blue/black. Iodine is used to indicate whether starch is present in a solution. If starch IS present, the indicator will turn dark blue/black. FOR WHAT PURPOSE WE USE STARCH-IODINE INDICATOR PAPER
Eriochrome Black T is a common indicator used in EDTA titrations, not Echnrome Blue Black T. Eriochrome Black T changes color from blue to magenta when it binds to the metal ions being titrated with EDTA, indicating the endpoint of the titration.

Iodine is not an indicator of glucose. Iodine is primarily used as an indicator for the presence of starch in a solution through the formation of a blue-black color complex. Glucose can be tested using methods such as Benedict's solution, Fehling's solution, or glucose test strips.
Iodine is commonly used as a chemical indicator for the presence of starch. When iodine comes into contact with starch, a blue-black color change occurs, making it easy to visually detect the presence of starch in a solution.
