Nicl2

Need help! Acidic, basic or neutral NiCl2?

NiCl2 (s) + 6H2O Â Â [Ni (H2O) 6] 2 + + 2Cl (blue)

C (aq) is not significantly hydrolyzed (HCl vs. strong acid)

[Ni (H2O) 6] 2 + + H2O Â Â [Ni (H2O) 5 (OH)] + + [H3O] +

pKa ~ 10 makes it slightly acidic

Need help! Is NiCl2 Acidic, Basic or Neutral? 3
I have no idea. Wikipedia says it is an acid, so what is the hydrolysis reaction?
Thank you very much!
