Parts per million (ppm) is a common way to express small concentrations of a solute in water. a sample of tap water that is 25 ppm cl−cl− contains 25 grams of cl−cl− for every 1,000,000 grams of water. which units are numerically equal to ppm for dilute aqueous solutions?

a. μg/l
b. cg/l
c. ng/l
d. mg/l
e. g/l

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
