There is a wide range of topics which include saline, sodic, acidic, eroded, compacted, and organic soils. |
A scintillometer could make a radiometric survey at the same time which would distinguish potassic from sodic granites. |
The Lake George center, for instance, had three emplacements, one potassic, another sodic, and yet another with a mixed composition. |
The filtered fluid gives on addition of sodic chloride a precipitate of oxychloride. |
It is prepared by dropping a strong solution of antimony trichloride into a saturated solution of sodic phosphate. |
Solutions of the chloride also give a heavy precipitate of lead sulphate, when treated with a solution of sodic sulphate. |
