At the start, the concentration of acetic acid is 0.1 M. After dissociation, the concentrations at equilibrium will be:- (CH3COOH)=0.1−α- (CH3COO−)=α- (H+)=α Substituting these into the Ka expression gives:Ka=α⋅α0.1−α=α20.1−α Step 3: Simplify the equation...
the concentration of salt is higher in their blood than their surrounding water. they absorb a controlled amount of water through the mouth and the gill membranes. due to this intake of water, they produce large quantities of urine through which a lot of salt is lost. the salt is replaced...
