thomaster · Answer

sodium bicarbonate which is secreted by the duodenum neutralizes gastric acid.

$\large\sf NaHCO_3 + HCl \rightarrow NaCl + H_2O + CO_2$

anonymous · Answer

correcto :)

abbie · Answer

so for an experiment to prove that bicarbonate neutralizes gastric acid what can I do? any ideas? I know I can use baking soda and a PH measurer but can someone tell me it in steps please???

agent0smith · Answer

Couldn't you just use baking soda and hydrochloric acid?

abbie · Answer

I can but what exactly do I do with those

abbie · Answer

and what is hydrolic acid?

agent0smith · Answer

Hydrochloric acid is hydrochloric acid... 

I guess measure the pH of HCl before, and after, pouring in some baking soda.

abbie · Answer

so the oh is 1.42 of the hydrolic acid

abbie · Answer

then I pour in the baking soda and measure the ph again?

abbie · Answer

ok I did that now i dont know how to measure it

agent0smith · Answer

Idk, you can use litmus paper...

thomaster · Answer

either measure the pH with some electrodes (a pH probe) or with indicator paper.
You could also do it colorimetric.
