The tablet was crushed and 4.3628g of the antacid was added to 200 mL of stimulated stomach acid. This was allowed to react and then filtered. It was found that 25 mL of this partially neutralized stomach acid required 8.50 mL of NAOH solution to titrations it to a methyl red endpoint. It took 21.54 mL of this NAOH solution to neutralize 25 mL of the original stomach acid. a)How much of the stomach acid had been neutralized in the 25 mL sample which was titrations? (Show work) B) how much stomach acid was neutralized by the 4.3628 g sample used? (Show work) C)How much stomach acid would have been neutralized by the original 5.6832 g tablet? (Show work)
