Description
Inorganic compound, complex compound transitional metal bismuth, organic compound thiourea and inorganic nitric acid. From water solutions crystallizes as monohydrate.
Reaction between bismuth(III) nitrate and thiourea
Chemical equation:
For preparation of
100.00g of nitratopentakis-tiokarbamatbismuth(III) nitrate monohydrate а 61.12g of bismuth(III) nitrate pentahydrate and 47.96g of thiourea is required.Add to the flask with thiourea solution a bismuth(III) nitrate solution with stirring. After reaction will stop, filter the solution and use it for crystal growing.
Notes
The solution is hydrolyzed with hydrogen sulphide emission after few weeks.
Keep in its original form or under several layers of varnish at average humidity and room temperature. Do not keep crystals near heaters.
Soluble in water.
