`50mL` of standard gold sol requires `=0.05mg` of gelatin Therefore, `10mL` of standard gold sol requires `=(0.05)/(50)xx10=0.01mg` of gelatine `:.` Gold number `=0.01`
5 ml of standard gold sol, needs 0.5 mg of gelatin for its protection from coagulation, calculate the gold no of gelatin.
100 mL of a standard sol required 240 mg of starch for its protection against coagulation, Calculate gold number of starch.
On addition of one ml solution of 10% NaCl to 10 ml gold solution in the presence of 0.009 g of an anticoagulant, the coagulation is prevented. What is the gold number of anticoagulant?
10^(-4)g of gelatian is required to be added to 100cm^(23) of a standard gold sol to just prevent its coagulation by the addition of 1cm^(3) of 10%NaCl solution to it. Hence the gold number of gelatain is
When 6xx10^(-5)g of a protective colloid was added to 20mL of a standard gold sol, the precipitation of latter was just prevented on addition of 2mL of 10%NaCl solution. The gold number of a protective colloid is
The coagulation of 200 ml of a colloidal solution of gold is completely prevented by adding 0.50 gm of starch to it before adding 1 ml of 10% NaCl solution. Calculate the gold number of starch.
