Use this kit to create fresh solutions of known pH values (4, 7 & 10) for calibrating pH meters or other purposes.
This set of capsules can be used to create a quick and reliable preparation of fresh solutions of known pH values for calibrating the PASPORT pH Sensor (such as PS-2102 and other pH sensors)
Contains one vial each, with 10 capsules per vial of pH 4.0, pH 7.0, and pH 10.0. Each capsule is sufficient to make 100 mL buffer solution. Includes preservative solution which contains a pH indicator and colors each buffer solution for easy identification.
Using distilled water, the user can formulate clear solutions accurate to ±0.02 pH unit. The dry powder remains stable.
Perform the following experiments and more with the pH Buffer Capsule Kit.

Students use a pH sensor to test the pH of a set of serial dilutions and make a connection between the pH value (& pOH) of a solution and its hydrogen ion (& hydroxide ion) concentration.
Students use a pH sensor to investigate how antacid tablets work and use a back titration method to determine how much of the active ingredient is found in one tablet.
Students use a pH sensor to explore the effect of excess atmospheric carbon dioxide on water pH.
Students use a pH sensor to conduct a strong acid and weak acid titration with a strong base.
