Ka and pH calculations for weak acids can be trick on the MCAT if you attempt a general chemistry approach.

Ice tables and quadratic equations are not only a waste of time, but nearly impossible without a calculator.

This video shows you my shortcut for skipping the ICE chart and skipping the quadratic equation for weak acid calculations.
