Distinguish between organic acid and mineral acid

Organic Acids:

organic acids are weaker.organic acids always contain carbon, hydrogen and oxygen. organic acids are naturally occurring. organic acids are found in plants and animals.Examples: Methanoic acid, ethanoic acid, lactic acid etc.

Mineral Acids:

Mineral acids are strong. Mineral acids are derived from one or more minerals found on Earth.Other than hydrogen, no other element is fixed in mineral acids.Example: Hydrochloric acid, sulphuric acid

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
