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

50 mL of standard gold sol. needs 0.05 mg of gelatin for its protection from coagulation. Calculate gold number of gelatin.

50 ml of standard gold sol needs 0.05 mg of gelatine for its protection from coagulation - Calculate gold number of gelatine.

5 ml of standard gold sol, needs 0.5 mg of gelatin for its protection from coagulation, calculate the gold no of gelatin.

5ml of standard gold sol, needs 0.5 mg of gelation for its protection from coagulation, calculate the gold no of gelation.

100 mL of a standard sol required 240 mg of starch for its protection against coagulation, Calculate gold number of starch.

1 mL of 10% NaCl solution on addition to 100 cm^(3) standard gold sol in presence of 10^(-4) gelatin just prevents the coagulation of that sol. Find the gold number of gelatin.

10^(-4) g of gelatin is required to be added to 100 ml of standard gold sol to just prevent its precipitation by addition of 1 ml of 10% NaCI solution to it. Hence the gold number of gelatin is:

300 mL of gold sol is mixed with 30 mL of 10% NaCl solution. The mass of haemoglobin in mg required to protect the gold sol from coagulation is (gold number of haemoglobin is 0.03)
