When sodium acetate dissolves in water the resulting pH is above 7. This is because Sodium ion reacts with water to produce hydroxide ions. O Sodium ion is the cation of a strong base and acetate is the anion of a weak acid. Acetate ion reacts with hydroxide ions to produce excess protons. none of these answers Knowing the pH of a solution will allow one to know the pOH as well. O True...

2. Label each of the following statement as True or False: Under chemical equilibrium, the concentration of the reactants is equal to the concentration of the products. a. b. Under chemical equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. In Le Chatelier's Principle, the term "stress" refers to the death of a loved one, too much workload, and the deprivation of food and sleep. c. d. In Le Chatelier's Principle, the term...

Laboratory 11, Equilibrium Control of a Reaction Name Chemical Equilibrlum: equilibrium is when the rates of the forward and reverse reactions are equal. Therefore, the concentration of all reactants and products remain constant. This is not to say that the reaction has ceased. It is a dynamic situation at chemical equilibrium with the rate of disappearance of reactants the same as the rate of appearance of reactants through the reverse reaction (the same for the rate of disappearance and appearance...
