It is a matter of memorization. There are only 6 common strong acids, some sources list 7 or 8. All other acids can be considered weak.
The six commonly listed strong acids are:
Hydrochloric acid: HCl
Hydrobromic acid: HBr
Hydroiodic acid: HI
Perchloric acid: HClO4
Nitric acid: HNO3
Sulfuric acid: H2SO4
Two acids sometimes cited as strong acids are:
Periodic acid: HIO4
Chloric acid: HClO3

Is it weak acid or strong acid when the position of a reaction lies to the left?
you cant really tell if its strong like that. you need indicator liquid to tell you if its an acid or a base and then tell if its strong by seeing the reaction.
Is formic acid strong or weak?
Electrolyte strength tell how well the acid conducts electricity. Formic acids are not strong electrolytes but rather very weak ones.
Is chloroacetic acid a weak or a strong acid?
It is a weak acid.
Acetic acid- strong acid or weak acid?
Weak.
Is phosphoric acid strong or weak acid?
