Sulfuric acid is very effective at transferring a hydroxide ion. This happens because the first beaker contains some vinegar ballinasloe or acetic acid which neutralizes the NaOH. When gases combine, they always do so in the same way provided that the temperature and pressure stays the same. For instance, and changes the solution from basic to acidic. This indicates the pH is near neutral. Each changing different colors at different pH values which allows the observer to determine more precisely where the solution in question falls on the pH scale.
Manufacturers place the strips in re-sealable plastic vials.Neutral gases, such as oxygen and nitrogen, do not change the color of the pH paper.Bottom half of the graphic: When the pitcher is then poured back into beakers 2, 3, 4 it is a pink solution.
