Stannic molybdate

Stannous and stannic molybdates have not been isolated. The addition of alkali molybdates to solutions of stannous salts causes precipitation of a blue oxide containing tin, possibly as stannic molybdate. 

Bersch refers to the blue modification of molybdenum oxide as a component (with stannic molybdate ) in the pigment he calls molybdenum blue. 

Some chemicals that are reported to stimulate glowing are chromates, molybdates, halides of chromium, manganese, cobalt and copper, and ferric and stannic oxides (.5,10) Chemicals found to be ineffective in retarding afterglow in a limited study were ammonium sulfate and sodium borates (10). ... 

Occluded hydrogen is more reactive chemically than the normal gas. Hydrogenated palladium precipitates mercury and mercurous chloride from an aqueous solution of the dichloride, without any evolution of hydrogen. It reduces ferric salts to ferrous potassium ferricyanide to ferrocyanide chlorine water to hydrochloric add iodine water to hydriodic acid 2 chromates to chromic salts ceric to cerous salts whilst cupric, stannic, arsenic, manganic, vanadic, and molybdic compounds are also partially reduced.3...
