Titanium dioxide

"Sodium persulfate" which is used in electronics is well suited.

Equipment needed

Tripod with clay triangle
Porcelain crucible
Gas burner

Test procedure


No harmful residue is produced.


Soluble titanyl sulfate is formed. If one wants to demonstrate titanium(IV)in a solid substance, one can appropriately convert this.


Conversion of titanium oxide


derived from "Titan", S. 451,[7] - there potassium hydrogen sulfate is used instead of sodium peroxodisulfate.
