How to solve ions
WebIn chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. Ion associates are classified, … WebWhen we break this up into its ions, we get H2 (aq) + SO4 (2−) (aq) + 2 Na+ (aq) + 2 OH− (aq) → 2 Na+ = SO4 (2−) (aq) + 2 H2O (ℓ). So we can "cancel" the 2 Na+ (aq) and the SO4 (2−) (aq) on each side. Okay. Then the resulting reaction is H2 (aq) + 2 OH− (aq) → 2 H2O (ℓ).

WebJul 4, 2024 · Omitting the water molecules bound to Cu 2+ for simplicity, we can write the equilibrium reactions as follows: The sum of the stepwise reactions is the overall equation for the formation of the complex ion: The hydrated Cu 2+ ion contains six H 2 O ligands, but the complex ion that is produced contains only four NH 3 ligands, not six. WebAug 29, 2024 · Solution Part a. Dissolving 1 mol of Al (NO 3) 3 in water dissociates into 1 mol Al 3+ and 3 mol NO 3- by the reaction: Al (NO 3) 3 (s) → Al 3+ (aq) + 3 NO 3- (aq) Therefore: concentration of Al 3+ = 1.0 M concentration of NO 3- = 3.0 M Part b.
