hypothesis : latex coagulates in acid.

procudure 2 : pour latex into the 3 beakers
procedure 3 : pour the alkaline solution ( NH3+) to beaker A and pour acidic solution to beaker B.
procedure 4 : stir it well . any observation is recorded.
observation :latex is coagulate in beaker B. ( and the smell is super duper chocking )
