A cocaína é um pó branco cristalino obtido na forma de sal de hidrocloreto extraído
das folhas de coca, conforme ilustra o Esquema 1 a seguir:
Fonte: HARRIS, D. C. Explorando a Química Analítica. Tradução e revisão técnica:
Júlio Carlos Afonso, Mauro dos Santos de Carvalho, Milton Roedel Salles e Oswaldo
Esteves Barcia. 4. ed Rio de Janeiro: LTC, 2011. p. 169.
Nos anos de 1980 os traficantes de drogas descobriram o valor superior da forma da
base livre da cocaína ou “crack”. O “crack” é solúvel em solventes orgânicos e em
membranas celulares. O hidrocloreto iônico é solúvel em água, mas não em
membranas celulares, e a sua ação fisiológica é mais lenta do que a do “crack”. A
base livre é obtida através da reação do hidrocloreto com bicarbonato de sódio
segundo a reação (HARRIS et al., 2011):

Suponha que você atue como legista da área da saúde e eventualmente seja
necessário fazer análises de substâncias ilícitas.
Dessa forma, responda as questões a seguir:
(Dado: K = 1,00x10 ; K = 2,6x10 ; pH = -log [H ])
a) No primeiro esquema (Esquema 1), identifique os pares ácido-base conjugados,
indicando qual espécie é ácida e qual é básica.
b) Calcule o pH de uma solução 0,0453 M de cocaína.
c) Caracterize a cocaína como ácida, neutra ou básica.
