Concentrated hydrochloric acid is present in your stomach. It aids in digestion but is also responsible for the burning sensation of acid reflux.
This strip can also test other acids when concentrated as noted by the amount in mM. You can use this in a science project as a serial dilution exercise using a dropper & graduated cylinder. Warning: These acids are highly corrosive when concentrated. Experiment only with the supervision of a teacher. Wear safety goggles & shield, lab coat & apron, proper gloves & in a fume hood if possible. Add acid to water not the other way around.
You can also view the structure of these acids with our 3D Molecular Model Builder. It doesn't always recognize chemical formulas but will display correctly if the chemical compound names are used.
