Resumo: The present investigation aimed to analyze and classify problem situations of Common Concentration of Solutions present in Chemistry textbooks, according to the theory of Conceptual Fields. For the analyses, the six Chemistry works approved by the PNLD 2018 were considered and the volume of the 2nd year of each work was selected, as they include the content of Common Concentration of Solutions. The research analyses, carried out in the light of the Conceptual Fields theory, showed that situations of Common Concentration are associated with the Multiplicative Conceptual Field and are classified as Simple Proportion. It was also identified that situations may vary in subclasses: Partition, One-to-Many Multiplication, Quota and Fourth Proportional. Therefore, the results showed that the problem situations of Common Concentration of Solutions are presented in the textbooks analyzed through contexts close to the reality of the students and that mathematical notions such as multiplication, division, operations with decimal numbers, fractions, proportion, volume and conversion of measurement units, as well as different mathematical representations, such as algebraic, numerical, tabular, graphic and natural language are essential for solving Common Concentration problem situations in Chemistry.

Para los análisis se consideraron los seis trabajos de Química aprobados por el PNLD 2018 y se seleccionó el volumen del 2º año de cada trabajo, ya que incluyen el contenido de Concentración Común de Soluciones. Los análisis de la investigación, realizados a la luz de la teoría de los Campos Conceptuales, mostraron que las situaciones de Concentración Común están asociadas al Campo Conceptual Multiplicativo y son clasificadas como de Simple Proporción. También se identificó que las situaciones pueden variar en las subclases: Partición, Multiplicación Uno a Muchos, Cuota y Cuarto Proporcional. Por lo tanto, los resultados mostraron que las situaciones problema de Concentración Común de Soluciones se presentan en los libros de texto analizados a través de contextos cercanos a la realidad de los estudiantes y que nociones matemáticas como multiplicación, división, operaciones con números decimales, fracciones, proporción, volumen y la conversión de unidades de medida, así como diferentes representaciones matemáticas, como el lenguaje algebraico, numérico, tabular, gráfico y natural, son esenciales para resolver situaciones de problemas de Concentración Común en Química.The present investigation aimed to analyze and classify problem situations of Common Concentration of Solutions present in Chemistry textbooks, according to the theory of Conceptual Fields.
