A student pipetted exactly 50.00 mL of 0.1038 M HCl into a 250-mL Erlenmeyer flask containing 0.3735 g of an antacid tablet. The solution was heated and boiled to remove any
CO2. Approximately 25 mL of water and three drops of phenolphthalein indicator was added
to the Erlenmeyer flask containing the HCl and antacid tablet. A 50 mL buret was rinsed and
filled with a 0.1017 M NaOH solution. The initial volume of the buret was read and recorded
as 2.30 mL. The NaOH solution was carefully added to the antacid/HCl solution until a
permanent very slight pink coloration was noticed. The buret was read again and recorded as
22.82 mL. Calculate the acid equivalent (g HCl/g antacid) of the antacid tablet.

some of the qualities most frequently associated with the baroque are grandeur, sensuous richness, drama, vitality, movement, tension, emotional exuberance, and a tendency to blur distinctions between the various arts.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
