Answer 2

The reaction between sodium hydroxide (NaOH) and hydrogen gas (H2) is related to the phenol red test and the splint test, which are used to diagnose airway disorders such as aspiration, reflux, and bronchitis.

In the phenol red test, phenol red solution is swallowed and changes color based on the pH of the gastric juice. If there is acid reflux, the stomach contents will be acidic, causing the phenol red to change color from yellow to red. The addition of NaOH will neutralize the acid, resulting in a change in the color of the phenol from red back to yellow.

In the splint test, a flexible splint is placed in the airway to detect the presence of reflux. The splint is covered with a phenol red solution, and if there is acid reflux, the phenol red will change color from yellow to red. Neutralizing the acid with NaOH will cause the color to change back to yellow, indicating the presence of reflux.

In both tests, the reaction between NaOH and H2 is used to determine the presence of acid reflux by neutralizing the acid and changing the color of the phenol red solution. These tests help diagnose airway disorders and guide treatment decisions.
