Description
Precursors
Reaction between metal silver and nitric acid
Chemical equation:
For preparation of
Add acid solution to the flask, then add silver pieces, shavings or powder and stir it until gas emission will stop.100.00
g of silver(I) nitrate а 63.50
g of pure silver and 114.13
g of 65%
acid is required.Reaction between silver oxide or hydroxide and nitric acid
Chemical equation:
For preparation of
Add acid to the flask, then add small parts of silver compound with stirring until it will totally dissolve . After reaction will stop, filter the solution and use it for crystal growing.100.00
g of silver(I) nitrate а 68.21
g of silver oxide or 73.51
g of silver hydroxide and 57.07
g of 65%
acid is required.Influence of impurities
Additions of other metals nitrates can influence on crystal color or shape.Notes
Dissolving is endothermic, solution cools much, so use hot water or using heat.
Storage conditions
Store in its original form or under several layers of varnish at average humidity and room temperature. Do not store in matchboxes or cotton wool and do not heat.
