Middle school ion characteristics test kit

The middle school ion characteristics test kit allows for 6 tests of the following ions: Ag⁺, Cu²⁺, Fe²⁺, Fe³⁺, Zn²⁺, Cl^-. Consisting of a set of pre-dosed solutions, the 'middle school ion characteristics tests' kit significantly reduces the preparation time for the ion characteristics test practical work by reducing both the materials used for dilutions and the glassware present in the laboratory. The provided solutions have been studied to clearly visualize a precipitate within a solution. The student observes during the experiments that they are working in two distinct environments. The quantities of ionic compounds in the dropper bottles are minimized to reduce the risks associated with these products in the laboratory. By favoring plastic packaging, the risks of breakage, cuts, and the cost of recycling chemical product packaging are minimized.

5 plastic drop bottles of 30 mL each containing: - 1 solution of copper sulfate - 1 solution of iron(II) sulfate - 1 solution of iron(III) sulfate - 1 solution of zinc nitrate - 1 solution of sodium chloride 1 yellow glass drop bottle of 30 mL containing: - 1 solution of silver nitrate to identify the anion. 1 plastic drop bottle of 60 mL containing: - 1 solution of sodium hydroxide to identify the cations.
