Neutralizing acids and bases

Neutralizing acids and bases

Students in Steve Ogram’s chemistry classes performed a lab experiment on Thursday, May 9. The purpose of the lab was to teach students about the process of titration. The lab was done in groups of four or five students.

The lab started off with students pouring a base into a graduated cylinder. An indicator was then poured into the cylinder, as a way to indicate when the reaction was neutralized.

Sophomores Naomi Soto and Brianna Flor watch the reaction intently. Students were encouraged to find the exact point of neutralization in the reaction, getting the solution to turn to a light pink color. ““I thought it was interesting because the indicator needed the perfect balance to turn pink”

As the test on the material approached, some students enjoyed that the lab gave them a real perspective on how the process worked, rather than just a textbook definition.

“Well, the lab was actually really interesting,” sophomore Danielle Cushman said.  “I thought it was good that we got a visual representation of what we were learning”

Even though it was not required, some students challenged themselves to find the exact point of neutralization. It was difficult at times because even one drop could neutralize the solution.

“It was hard to pinpoint the reaction,” sophomore Briana Flor said. “it would turn pink but then disappear because there wasn’t enough phenolphthalein to neutralize the reaction.”
