Question

Cyanide used in nepheloturbidometry as a salt of

• A. Ag
• B. Au
• C. Na
• D. K

Hint:

In nepheloturbidometry, silver cyanide (AgCN) is the common cyanide salt due to its precipitate formation causing turbidity.

Answer 1

The Correct Option is A

- Nepheloturbidometry is an analytical technique used to measure the turbidity or cloudiness of a solution, often due to suspended particles.
- In nepheloturbidometry, cyanide ions are commonly used as silver cyanide (AgCN) salt.
- Silver cyanide forms a precipitate that scatters light, which is measured to determine the concentration of analytes.
- The salt of silver (Ag) is preferred because of its stable complex formation with cyanide and well-defined turbidity properties.
- Salts of gold (Au), sodium (Na), or potassium (K) cyanide are not typically used for this purpose in nepheloturbidometry.
