VOLUMETRIC SOLUTION OF NITRATE OF SILVER.
(Nitrate of Silver, = 170.)
Take of
Nitrate of Silver | 170 grains |
Distilled Water | a sufficiency |
Put the nitrate of silver into the 10,000 grain flask, and, having half filled the flask with water, allow the salt to dissolve; then dilute the solution with more water until it has the exact bulk of 10,000 grain-measures. The solution should be kept in an opaque stoppered bottle. 1,000 grain-measures of this solution contain 110th of a molecular weight in grains of nitrate of silver (or 17.0 grains).
Grammes and cubic centimetres may be employed instead of grains and grain-measures, but for convenience 110th of the numbers should be taken. 100 cubic centimetres contain 1100th of a molecular weight in grammes of nitrate of silver (or 1.7 gramme).
It is used in testing the following substances:—
