varies with the concentration of the solution and the range of
temperature as shown in the table.

=59. Error Due to Impurities.=—The fact that equal per cents of solid
bodies in solution affect the specific gravity in different degrees
has already been noted. The specific gravities of the solutions of the
common sugars, however, are so nearly the same for equal per cents of
solid matter in solution as to render the use of a brix hydrometer
quite general for technical purpose. For the mineral salts which often
occur in sugar solutions the case is quite different. A twenty per cent
solution of cane sugar at 17°.5 has a specific gravity 1.08329 and of
dextrose 1.08310, practically identical. But a solution of calcium
acetate of similar strength has a specific gravity of 1.0874; of sodium
sulfate 1.0807, and of potassium nitrate 1.1359. This latter number
would correspond to a sugar content of nearly twenty-seven per cent.
The brix scale can, therefore, be regarded as giving only approximately
the percentage of solid matter in sugar solutions and, while useful in
technical work, should never be relied upon for exact analytical data.
