Question

Based on the following description of reaction that form complex ions right the balance molecular and net ionic equation for the reaction so the physical form of species and underline any solids RATORY 34 b. Solid nickel(II) Auoride is dissolved in the presence of aqueous potassium fluoride by forming a soluble complex ion between nickel(II) and fuoride ion, with a coordination number of four. Molecular: Net-ionic c Aqueous cobalt(II) iodide reacts with aqueous ammonia to form a soluble complex ion between cobale(lID) and ammonia, with a coordination number complex ion berween cobalt(II) and ammonia, with a coordination number of six. Molecular Net-ionic:
