A (total or full) ionic equation shows the reaction/movement/placement of all ions, including spectator ions. The net ionic equation is the substance represented in its most reduced form. It shows only the soluble, strong electrolytes that are reacting (these are represented as ions) and the spectator ions are omitted.

Most of the cations and anions described above can combine to form solid compounds that are usually known as salts. The one overriding requirement is that the resulting compound must be electrically neutral: thus the ions Ca 2+ and Br – combine only in a 1:2 ratio to form calcium bromide, CaBr 2 .

The spectator ions in KOH(aq) and HNO 3 (aq) are: K + (aq) and NO 3 – (aq) How to Identify and List the Spectator Ions in a Reaction Step I : Write the equation (with chemical formulas) for which spectator ions are to be determined. Step II : Express each of the reactants and products in terms of its cations and anions.
Anion vs. Cation Dealkalization. Strong base anion resins may be used for demineralization or dealkalization, while weak base anion resins work best for removing acids and organics from water. Anion dealkalizers are primarily used to remove alkalinity from boiler feedwater with a low-to-moderate amount of total dissolved solids (TDS).

NH4^1+ and SO4^2- are present. When these two are combined the 1+ charge of ammonium and the 2- charge of sulfate are flipped so that you'd have (NH4)2 SO4 where all the numbers are subscripts.
CuS. anion: S. cation: Cu. anion charge is -2 (second from right on periodic table). cation charge is therefore 2+. Name is copper sulfide. Why not sulfur? Because Sulfur creates lots of ions with fancy names. Sulfite is S03. Sulfate is S04. S02 happens to be stable and poisons the earth as sulfur dioxide.

Jul 10, 2014 · Also, the ones formed by KI (aq) + Pb(NO3)2 (aq) and KI (aq) + CuSO4 (aq) were yellow because both resulting precipitates had iodide ions in them. However, we were curious why a yellowish brown precipitate was produced when potassium iodide and copper(II) sulfate were mixed, because the resulting precipitate involved both copper and iodide.

Split strong electrolytes into ions (the complete ionic equation). Cross out the spectator ions on both sides of complete ionic equation. Write the remaining substances as the net ionic equation. Note: charges in a net ionic equation are conserved.
When all the H ions are removed from the “-ic” acid, the anion’s name ends with “-ate.” 2. When all the H ions are removed from the “-ous” acid, the anion’s name ends with “-ite.” 3. The names of anions in which one or more but not all the hydrogen ions have been removed must indicate the number of H ions present.

You probably ran a bit of electrochemistry. The salt water probably allowed electrons to be transfered between the aluminum foil and the CuSO4. You're also probably at least partially right with the Cl- ions combining with the Al2O3 to give a clean Al surface for the redox reaction to occur on. Try hooking up a ampmeter to it and measure the ...

When an ionic compound dissolves, the relative concentrations of the ions introduced into the solution depend on the chemical formula of the compound. For example, a 1.0 M solution of NaCl is 1.0 M in Na + ions and 1.0 M in Cl – ions. Similarly, a 1.0 M solution of Na 2 SO 4 is 2.0 M in Na + ions and 1.0 M in SO 4 2– ions.

So with small cations of Copper and large anions of Sulfate, they compress and become a structure like the one below, with the smaller cations positioned between the larger anions. Intermolecular Forces: Since this is an ionic bond the Copper positive ion will be attracted to the positive ions of Sulfate and vice versa.

The primary valence is the number of negative ions needed to satisfy the charge on the metal ion. In each of the cobalt(III) complexes previously described, three Cl-ions are needed to satisfy the primary valence of the Co 3+ ion. The secondary valence is the number of ions of molecules that are coordinated to the metal ion. Werner assumed that ...
