Answer (1 of 3): When sodium nitrite (NaNO2) is dissolved in water, the resulting solution is basic, but when sodium nitrate (NaNO3) is dissolved in water, the resulting solution is neutral. NaNO2 = Na+ + NO2- NO2- + H2O = HNO2 + OH- The solution is basic NaNO3 = Na+ + NO3- NO3- is the con...
Abstract. Aqueous salt solutions play an important role in nature because of their effects on environmental biogeochemical processes and on structural properties of biomolecules. Upon dissolution, salts split in ions that are solvated. Water in hydration shells is subjected to molecular motions that can be monitored by (1)H T1 NMR relaxometry.
