For each salt, state the net-ionic equations for the interactions of each ion with water (State NR if no reaction occurs). Define why each salt solution is acidic, basic, or neutral. NaC2H3O2: Na+ + H2O ------>
C2H3O2- + H2O ----->
NH4Cl: NH4+ + H2O ----->
Cl- + H2O ----->
Na2CO3: Na+ + H2O ------->
CO32- + H2O ------>
