Which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of ni2+ is increased? view available hint(s) which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of is increased? ni(oh)2(s)⇌ni2+(aq)+2oh−(aq) [ni(h2o)6]2+(aq)+3en(aq)⇌[ni(en)3]2 +(aq)+6nh3(aq) ni2+(aq)+6nh3(aq)⇌[ni(nh3)6]2+ nis(s)⇌ni2+(aq)+s2−(aq)
