If 5.35mL of 0.1000 M NaOH solution is needed to just neutralize excess acid after 20.00 mL of 0.1000 M HCl was added to 1.00 g of an antacid, how many moles of acid can the antacid counteract per gram?
The solution is then allowed to come to equilibrium. Analysis of the equilibrium mixture shows that the concentration of hydroxide ions is 0.000464 M. Calculate the Keq at 25 degrees Celsius for the reaction.
