2Cu+6HNO_3\xrightarrow~2Cu(NO_3)_2+3H_2O+2NO_2

2Cu(NO_3)_2~+~2Na_2CO_3~+~H_2O\xrightarrow~CuCO_3~\cdot~Cu(OH)_2~+~4NaNO_3~+~CO_2

2HNO_3+Na_2CO_3\xrightarrow~2NaNO_3+CO_2+H_2O

CuCO_3~\cdot~Cu(OH)_2\xrightarrow{\Delta}~2CuO+H_2O+CO_2

CuO+H_2SO_4\xrightarrow~CuSO_4+H_2O

CuSO_4+Mg\xrightarrow~MgSO_4+Cu

H_2SO_4+Mg\xrightarrow~MgSO_4+H_2

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
