Answer and explanation;
-Strong acids and bases are defined as compounds that completely ionize in water or aqueous solution. Weak acids and bases only partially dissociate.
A strong acid will fully dissociate in water to form H+ ions.
HCl + H2O---> H3O+ + Cl-
This reaction is non-reversible. After dissolution, only a very very minute concentration of HCl itself remains in the solution, as most of the diluted HCl has dissolved into ions.
Ka = [H+] [Cl-] / [HCl]
The same applied for bases. The only difference is that the base dissociates to form OH- ions instead.
Strong and weak bases will depend likewise on whether the reaction is reversible.
A strong base will completely dissociate to give more OH- ions.
An example of a strong base;
NaOH + H2O ---> Na+ + OH- + H2O
Kb = [Na+] [OH-] / [NaOH]
Pitfall traps (pitcher plants) trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria. Flypaper traps use a sticky mucilage. Snap traps utilise rapid leaf movements. Bladder traps suck in prey with a bladder that generates an internal vacuum.
Auricular Myiasis refers to fly larvae in the ear tissue. Myiasis is the inversion of body tissue of animal by the larvae of diptera or two winged flies. Myiasis parasitic infection by the fly larvae inside the while feeding on the tissue.
