Resumo: The objective of this research work was to study the synthesis of metallic salts and to analyze their properties. For this purpose, tests were carried out using basic and acid solutions. These tests allowed to identify that the reaction of aluminum in the presence of sulfuric acid is an exothermic reaction whose first stage is the formation of the tetrahydroxoaluminate (III) ion complex, a process in which a significant amount of heat is released from the system and a large amount of hydrogen gas for the oxidation of aluminum, a second stage in which sulfuric acid was added to neutralize the basicity of the solution transforming the complex into disulfate-aluminate (III), Then a third stage consisted in subjecting the solution in an ice bath to decrease the solubility of the complex and the formation of whitish crystals and finally the removal of excess crystals by washing with ethanol, these tests revealed the importance of excess sulfuric acid in the stabilization of the aluminate ion and the ease of the complex ion to bind to water molecules, thus determining important properties of the reaction as the type, orientation, solubility and the intermediates affected by the metal catalysis.

Para ello, se realizaron ensayos utilizando soluciones básicas y de tipo ácido. Estas pruebas permitieron identificar que la reacción del aluminio en presencia de ácido sulfúrico es una reacción exotérmica cuya primera etapa es la formación del complejo ión tetrahidroxoaluminato (III) proceso en el cual se libera una cantidad de calor importante desdee el sistema    y una gran cantidad de hidrógeno gaseoso para la oxidación del aluminio, una segunda etapa en la cual se adicionó ácido sulfúrico para neutralizar la basicidad de la solución transformando el complejo en disulfatoaluminato (III), posteriormente una tercera etapa que consistió en someter la solución en el baño de hielo para disminuir la solubilidad del complejo y la formación de cristales blanquecinos y por último la remoción del exceso de cristales mediante lavado con etanol, estas pruebas nos revelaron la importancia del exceso de ácido sulfúrico en la estabilización del ion aluminato y la facilidad del ion complejo para unirse a las moléculas de agua, determinando de esta manera propiedades importantes de la reacción como el tipo, la orientación, solubilidad y los elementos intermedios afectados por la catálisis metálica.O objetivo deste trabalho de pesquisa foi estudar a síntese de sais metálicos e analisar suas propriedades.

Esses testes permitiram identificar que a reação do alumínio na presença de ácido sulfúrico é uma reação exotérmica cuja primeira etapa é a formação do complexo iônico tetrahidroxoaluminato (III), processo em que uma quantidade significativa de calor é liberada do sistema e uma grande quantidade de hidrogênio gasoso para a oxidação do alumínio, uma segunda etapa na qual foi adicionado ácido sulfúrico para neutralizar a basicidade da solução transformando o complexo em dissulfatealuminato (III), posteriormente uma terceira etapa que consistia em submeter a solução a o banho de gelo para diminuir a solubilidade do complexo e a formação de cristais esbranquiçados e finalmente a remoção dos cristais em excesso por lavagem com etanol, esses testes revelaram a importância do excesso de ácido sulfúrico na estabilização do íon aluminato e a facilidade do íon complexo para ligam-se às moléculas de água, determinando assim propriedades importantes reação, como tipo, orientação, solubilidade e intermediários afetados pela catálise de metal.Sapienza Grupo Editorial2021-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed articleArtículo revisado por paresArtigo avaliado pelos paresapplication/pdfhttps://journals.sapienzaeditorial.com/index.php/SIJIS/article/view/14310.51798/sijis.v2i4.143Sapienza: International Journal of Interdisciplinary Studies; Vol. 2 No. 4 (2021): Interdisciplinary studies and essays: Miscellaneous; 2-8Sapienza: International Journal of Interdisciplinary Studies; Vol. 2 Núm. 4 (2021): Estudios y ensayos interdisciplinarios: Miscelánea; 2-8Sapienza: International Journal of Interdisciplinary Studies; v. 2 n. 4 (2021): Estudos e ensaios interdisciplinares: Miscelânea; 2-82675-9780reponame:Sapienza (Curitiba)instname:Sapienza Grupo Editorialinstacron:SAPIENZAenghttps://journals.sapienzaeditorial.com/index.php/SIJIS/article/view/143/67Copyright (c) 2021 Dennis Renato Manzano Vela https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessManzano Vela , Dennis Renato 2022-12-26T21:35:56Zoai:ojs2.journals.sapienzaeditorial.com:article/143Revistahttps://journals.sapienzaeditorial.com/index.php/SIJISPRIhttps://journals.sapienzaeditorial.com/index.php/SIJIS/oaieditor@sapienzaeditorial.com2675-97802675-9780opendoar:2023-01-12T16:42:49.232752Sapienza (Curitiba) - Sapienza Grupo Editorialfalse
