Answer: At equilibrium , there are 0.274 moles of
Explanation:
Moles of = 0.682 mole
Moles of = 0.440 mole
Volume of solution = 2.00 L
Initial concentration of =
Initial concentration of =
Equilibrium concentration of =
The given balanced equilibrium reaction is,
Initial conc. 0.341 M 0.220 M 0 M
At eqm. conc. (0.341-x) M (0.220-x) M (2x) M
Given : (0.341-x) M = 0.258 M
x= 0.083 M
Thus equilibrium concentartion of = (0.220-0.083) M = 0.137 M
Thus moles of at equilibrium =
At equilibrium , there are 0.274 moles of
Answer: A weak acid solution consists of mostly nonionized acid molecules.
Explanation:
Strong electrolytes are those solutions which undergo complete dissociation when dissolved in water. The dissociation of strong electrolytes is given by a right arrow.
Weak electrolytes are those solutions which do not undergo complete dissociation when dissolved in water. The dissociation of weak electrolytes is given by a rightleft arrow.
Weak acids are those substances which dissociate partially to give ions when dissolved in water. Thus most of molecules remain unionized in solutions.
Strong acids are those substances which dissociate completely to give ions when dissolved in water.
