In a titration, if you are told that the acid and base react in a 2:1 molar ratio. You have determined that you required 22.50mL of a 0.1M NaOH solution to perform the titration with an acid. How many moles of the acid do you have

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

Ithink that one is (c)
