The paper presents the results of eye-tracking research run in order to determine students' strategies of balancing chemical equations for the reactions between adds and hydroxides which were illustrated by the example of the reaction between sulfuric acid (VI) and sodium hydroxide as well as between sulfuric add (VI) and aluminium hydroxide. The research has shown that 3rd grade university students at the bachelor level of chemistry with biology use different strategies, even when they solve similar problems.
