“…Research on chemistry misconceptions in acids-bases has been done by Pinarbasi (2007), showing that Turkey undergraduate students have some general misconceptions on the concept of acid and base. Another similar misconception of acid-base has also been found by Cros et al (1986Cros et al ( , 1988; Nakleh and Krajcik (1994); Kala et al (2013); Damanhuri et al (2016);and Tumay (2016). In this regard, Ozmen and Yildirim (2005) argued that Chemistry includes a number of abstract concepts; therefore, most students have difficulties in understanding and learning these concepts.…”

The study was conducted to map the misconception pattern of chemistry prospective teachers who learned acid-base and argentometric titration. Further, it attempts to minimize misconception through a multiple representation model of learning chemistry with cognitive dissonance strategy. The first treatment was done on acid-base titration and the second treatment on argentometric titration materials. The multiple choice test with open reasons was administered to 30 undergraduate students. The finding shows that 28.6% students have the same pattern of misconception while learning in both of the courses. After the treatment, misconception decreased to 9.5% on the first treatment, and 9.4% on the second treatment. The model was found to be suitable to decrease the misconception, but could not change the misconception into "zero misconception", especially for microscopic and symbolic representations.

“…La importancia creciente de este tema ha ido acompañada de la constatación de dificultades de enseñanza y aprendizaje de estos conceptos, que afectan incluso a los estudiantes universitarios (Cross 1986;Zoller, 1990;Schmidt, 1991;Ross y Mumby, 1991;Nakhleh y Krajcik, 1994;Vidyapati y Seetharamappa, 1995;De Vos y Pilot, 2001;Drechsler, 2005).…”

Resumen: Los estudiantes que finalizan sus estudios de bachillerato (17 o 18 años) deberían ser capaces de comprender las conceptualizaciones macroscópica y microscópica del comportamiento ácido-base y la relación entre estos modelos conceptuales. Este trabajo tiene por objeto ver en qué medida estos estudiantes dominan estos conocimientos y explican las propiedades de ácidos, bases y sales, a partir de sus moléculas (iones y moléculas). El estudio realizado revela que tienen un pobre conocimiento conceptual y procedimental del comportamiento ácido-base de las sustancias y sus disoluciones. La mayoría tiene dificultades para diferenciar entre ion y átomo de un elemento y consecuentemente no disponen de recursos para interpretar propiedades de las sustancias tales como la disolución en agua y la conductividad eléctrica.Palabras clave: aprendizaje, evaluación, comportamiento ácido-base, soluciones acuosas. Understands the students of 2º of baccalaureate behavior acid-base behavior of the substances? Analysis of the learning difficultiesAbstract: By the end of their high school studies, students should be able to understand macroscopic and sub-microscopic conceptualization of acid-base behavior and the relationship between these conceptual models. The aim of this article is to ascertain whether or not grade 12 students have sufficient background knowledge to correctly explain the properties of acids, bases and salts from their constituent entities (ions or molecules). This study reveals that grade 12 students lack some of the necessary knowledge and skills to understand the acid base behavior of substances. They do not differentiate between the ion and atom of an element and consequently find it difficult to interpret the properties of substances such as solution in water and electrical conductivity.
