Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils prepare a solution from a solid substance and also prepare a solution by diluting a concentrated liquid substance.

Instructional Ideas

• Create a cross-curricular project with a health class in a unit about the digestive system
• Have learners analyze advertisements of various antacid tablets and compare the claims to their experimental findings
• Assign different brands of antacids to various groups in the classroom to compare results

Classroom Considerations

• Hydrochloric acid is corrosive, so take special care in handling
• Sodium hydroxide is caustic, so avoid direct contact with skin
• Always add acid to water so splattering is less likely to occur
• Ensure groups dissolve substances carefully, due to heat generation of certain materials

 

 

Pros

• Experiment is divided into two parts to allow for variances if needed
• Application of this experiment will engage learners of multiple learning styles

Cons

• None
