Adding these substances to a red cabbage juice. Place 25-30
mL of cabbage juice indicator solution into a clean, dry cup. Using
a straw, blow
your breath through the cabbage indicator solution. Use slower,
deeper breaths that come from your lungs rather than quick, shallow
breaths that primarily exhale air that was just
inhaled. This step may take 5-10 minutes or more. Take a break if
necessary. Observe any change in color to see if the solution is
remaining neutral or becoming more
acidic or basic.
