`50 mL` of standard gold solution needs `0.05 mg` of gelatin for its protection from coagulation. Calculate the gold number of gelatine?

Text Solution

Verified by Experts

50r of standard gold sol requires =0.0 of gelatin
Therefore 1 or of standard gold sol requires =`0.05/50` of gelatin
Gold number =0.1
