Assume that a given solution contains ag+ or ba2+ or a mixture of both. a reasonable method for doing a qualitative analysis on this solution might be sketched out as follows (remember || means a precipitate forms and | means a solution remains. it is always assumed that solutions are separated from precipitates before adding the next reagent.) what is the precipitate formed at x in the above scheme?

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Anions are negative charged ions
