K+ and NO3- because KOH + HNO3 (yields) H2O + KNO3
The spectator ions in this is Na+
NO3- could also be considered a spectator ion because HNO3 is a strong acid, and so completely dissolves in water.
OH- and H+.
cl-
OH- 2H+ -> 2H2O(I) ywwww :)
This answer balances a theoretical reaction that does not occur in nature. 2KOH + Zn -> Zn(OH)2 + 2K Zn actually dissolves in strong base to form a so called "zincate" which was traditionally gven the formula of ZnO22- . It is now recognised that these zincate ions are hydrated to various degrees and one such ion is (Zn(OH)4)2- . Zn + 2KOHaq -> K2ZnO2aq +H2
