Product Information

Aligned with AP Chemistry Lab #7


When dissolved in water, acids dissociate to varying degrees. Strong acids quickly give up their protons, while weak acids dissociate only slightly. Therefore, the degree of dissociation, which indicates the strength of the acid can help in the identification of an acid. In this investigation, students determine the equilibrium constant of unknown acids and compare the data to known values to identify them. The kit comes with enough materials for 15 setups. A pH meter, required, is available separately. Note: Additional shipping fee required.

Chemical Contents:
Five Unknown Acids
Sodium Hydroxide, 0.1 M Solution
Phenolphthalein, 1% Solution

Additional Materials Required:
Analytical Balance
150 mL Beakers
50 mL Graduated Cylinders
250 mL Erlenmeyer Flasks
pH Meter
