Adding a base to their acidic liquid to complete a titration, juniors Mazz Siddiqui and Sofia Wu successfully neutralized the liquid. They did the math to find the molarity of the mixture. “The labs were the most interesting [part of chemistry] because I stood up and did something innovative,” Wu said. “The math [was sometimes challenging because it] needed to be correct in a chain reaction; you needed the first question to be right to do the next one right.”
