A substance which, when dissolved in water, causes an increase in the hydrogen ion content of the solution. A substance which, when dissolved in water, causes an increase in the hydroxide ion content of the solution. Weak Acids, Titration, Bronsted Acid, Bronsted Base, Conjugate Acids and Conjugate Bases, Lewis Acid, Lewis Base, Ion-product Constant of Water, pH. 2. Given the equation representing a homogeneous or heterogeneous equilibrium, write the mass action expression used to calculate K c or K p for the reaction. Given equilibrium concentrations or amounts of each reactant and product in a specified equilibrium, calculate the value of the equilibrium constant for the given reaction.
Equilibrium constants are temperature dependant.
Therefore a temperature change changes the value of the equilibrium constant and these constants are tabulated at given temperatures. Apply LeChatelier's principle to a given equilibrium when given the formula and whether or not the reaction is endothermic or exothermic. Given any K eq data, calculate concentrations of components of the equilibrium from the concentrations of other components. Given a Bronsted acid or base, give the formula of its conjugate. List by name and formula the six strong acids.
