🤓 Based on our data, we think this question is relevant for Professor Deluca's class at UTAH.
Write the balanced equation to establish a relationship between the reactants via stoichiometry
Reaction will appear as a double displacement reaction where counterions are switched
Products will appear as NaNO3 (from Na+ and NO3-) and Ni(OH)2 (from Ni2+ and OH-)
Reaction will appear as:
Ni(NO3)2 (aq) + NaOH (aq) → Ni(OH)2 (aq) + NaNO3 (aq)
Ni(NO3)2 (aq) + NaOH (aq) → Ni(OH)2 (aq) + 2NaNO3 (aq) (2 on both sides)
Balance Na and OH-, balanced reaction will appear as:
What volume of 0.100 M NaOH is required to precipitate all of the nickel(II) ions from 150.0 mL of a 0.249-M solution of Ni(NO3)2?
