Abstract This research was conducted with the purpose of carrying out the validation of the Chemical Simulator based on the topic Ionic Balance: Acid - Base was built from students' perception of the subject General Chemistry and the content of the topic. To this end the parti cipants were 38 students who took the subject of General Chemistry Parallel "C" from the Agronomic Engineering Department of Mayor de San Andrés University in term II/2018. Subsequently, after the design and the construction of the Chemical Simulator, in the secondary research the simulator was validated by means of the experts' criteria with the participation of 25 professors dedicated to Chemistry teaching. The experts' validation criteria were carried out in two dimensions: understanding and prediction, in both cases the assessment obtained was that categorized as acceptable; in general, the Chemical Simulator reaches an acceptable reliability coefficient according to the experts' criteria and it can, thus, be used as a pedagogical resource in Chemistry
