5c. Find equilibrium concentration as equation. 5d. Fill in the equilibrium constant expression with the appropriate number and/or equation. 5e. Solve mathematically (with calculator) or try the 5% rule simplification. 5f. Solve for "x" and then determine equilibrium concentrations for all species especially H+ and/or OH1-. If used 5% rule, check to make sure it is appropriate. |
5a. If needed, change mole into molarity (M). and state the initial conditions (into the ICE box).
5b. Figure out change and where "-" and "+" sign need for "x", Use Q if needed.
