Lactic acid is a weak acid, so it will react with a strong base, such as sodium bicarbonate (NaHCO3), to form a salt (sodium lactate) and water. If we have the 80% solution, to have 18 g we will need 22,5 g of this solution (18 * 100/80). Game over. Express the percent lonization to two significant figures. Lactate can potentially be cleared by urinary excretion in addition to PDH. Sodium lactate is also a natural component of the top layers of the skin and functions as part of the NMF or Natural Moisturizing Factor. This tells you that the reaction will always consume equal number of moles of lactic acid and of hydroxide anions, #"OH"^(-)#, delivered to the reaction by the sodium hydroxide solution.
