Determine if true or false: 1) ionic compounds, that dissolve well in water, and strong acids are both example of strong electrolytes. 2) Dynamic equilibrium means that the concentration of reactants and products is equal. 3) Strong acids react with some metals and produce hydrogen gas. 4) An Arrhenius base is a proton donor. 5) Many acids are monoprotic meaning they donate just one proton. 6) A buffer works best when there is equal, or close to equal, concentrations of the two components (often a weak acid and its conjugate base). 7) Ionic compounds, that dissolve well in water, and strong acids are both example of strong electrolytes. 8) The rate of a reaction can be determined by the following equation. Rate = change in [A] x time (where A is a product or reactant.)
