1 liter of a 1 M lithium hydroxide solution is added to 1 liter of a 1 M barium chloride solution, and a precipitate forms. What ions are left in solution after the reaction is complete? What ions are left in solution after the reaction is complete?
To determine the ions left in solution after the reaction is complete, we need to know the balanced chemical equation for the reaction between lithium hydroxide (LiOH) and barium chloride (BaCl2). Let's write the balanced equation first:
2LiOH + BaCl2 → 2LiCl + Ba(OH)2
From the balanced equation, we can see that lithium hydroxide reacts with barium chloride to produce lithium chloride and barium hydroxide as products.
Now, let's analyze the ions present in the solution after the reaction is complete:
1. LiCl (lithium chloride) is a salt that dissociates into ions in water, giving us Li+ (a lithium cation) and Cl- (a chloride anion) in solution.
2. Ba(OH)2 (barium hydroxide) is also a salt that dissociates into ions in water. In water, Ba(OH)2 dissociates into Ba2+ (a barium cation) and 2 OH- (hydroxide anions).
Therefore, the ions left in solution after the reaction between LiOH and BaCl2 is complete are Li+, Cl-, Ba2+, and 2 OH-.
