CaNO(3)2 is deliquescent. Are there viable alternatives? Is making in situ an option? e.g.
C a C O 3 + 2 H N O 3 ⟶ C a ( N O 3 ) 2 + H 2 C O 3 ⇌ C a ( N O 3 ) 2 + H 2 O + C O 2 {\displaystyle \mathrm{CaCO_3 + 2~HNO_3 \longrightarrow Ca(NO_3)_2 + H_2CO_3 \rightleftharpoons Ca(NO_3)_2 + H_2O + CO_2}}
Any opinions?
