Help me create an experiment for the question: How is stomach acid neutralized in the small intestine?

@thomaster think you can help me out again?

thomaster · Answer

The duodenum secretes sodium bicarbonate to neutralize stomach acid (hydrochloric acid)
This is the reaction: $NaHCO_3 + HCl \rightarrow NaCl + H_2O + CO_2$ 
As you see this reaction produces a salt (HCl) and a salt in solution conducts electricity.
As an experiment you could measure the conductivity of stomach acid and stomach acid with sodium bicarbonate added. When you add the bicarbonate the conductivity will rise.

Sorry the salt is NaCl not HCl xD
