A student prepares a solution of potassium nitrate KNO3 containing 95 g dissolved at 40c. This solution is - a) unsaturated
b) none of the above
c) saturated
d) supersaturated

Yes i think so not 100 percent sure though

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
