4. This whole thing is silly. An aqueous solution of sodium carbonate has basic pH because carbonate ions hydrolize to yield hydroxide ions plus bicarbonate ions. Even just starting with sodium bicarbonate (baking soda), the pH is basic: around 8.3 for reasonable concentrations.Find the pH and fraction of dissociation (α) of a 0.100 M solution of the weak acid HA with K a-= 1.00 x 10 5. Since the K a value is not low and the concentration is high, it should be possible to use the ICE method (as opposed to needing to use the systematic method). + HA ↔ H + A-Initial 0.100 .
