The following data is obtained for coagulating a positively charged sol in 2 hours array |c|l| Conc. of Cl ⁻ in mol L ⁻¹ & Result 5 10⁻⁵ & Sol not precipitated 6 10⁻⁵ & Sol not precipitated 7 10⁻⁵ & Sol precipitated 8 10⁻⁵ & Sol precipitated 1 10⁻⁴ & Sol precipitated array What is the coagulating value of electrolyte for this sol?
Options
- A7 10⁻⁵
- B7 10⁻²
- C5 10⁻²
- D9 10⁻²
Correct answer
A. 7 10⁻⁵
Step-by-step solution
Coagulating value = Minimum concentration of Cl required for precipitation of the sol.
