VAS Laboratories Soil Sampling Reminders: Most surface samples are taken from a depth of 0 – 6" up to 8" as this is where management of fertilizers and soil amendments occur. For mobile nutrients (nitrate, sulfate and chloride) an additional profile (636" up to 38") should be collected in a separate bag with the sample depth labeled.
Its melts at 176oC and boils at 1935oC (anhydrous). Anhydrous Calcium Chloride is hygroscopic by nature which means it attracts moisture from the air to form a hydrated compound. Dihydrate Calcium Chloride is 77% Calcium Chloride so is still hygroscopic by nature, however to a lesser extent than anhydrous Calcium Chloride.

Sep 21, 2005 · 1. Calcium chloride (n=6) is a very good drying agent for a broad variety of solvents but is generally not compatible with hydroxy (alcohol, phenol), amino (amine, amide) and carbonyl (acid, ketone, ester) functions due to basic impurities such as Ca(OH) 2 and CaCl(OH). In addition, it tends to form adducts with those compounds as well.
