Principle involved in assay of calcium gluconate​:

Explanation:

Principle involved in assay of calcium gluconate are​:

• The assay of calcium gluconate relies upon a replacement complexometric titration. Magnesium forms a fancy with the mixture of indicator mordant black II which indicates the primary color.
• The magnesium-indicator complex is more stable compared to the calcium-indicator complex; hence calcium doesn't affect the magnesium-indicator complex. When titrated against disodium edetate, calcium and EDTA formed.
• When all of the calcium has been consumed, the drop of EDTA breaks the magnesium-indicator complex, allowing the free indicator to make a fancy with the magnesium. The endpoint is decided by detecting the second color at that point.
