En las salinas de Manaure se procesa la mayor cantidad de sal que se consume en Colombia, este proceso se conoce como evaporación, ya que mediante el calor se evapora el agua y solo queda un remante. Si una solución de NaOH (hidróxido de sodio) se hace reaccionar con H3PO4 (ácido fosfórico)y luego la solución resultante es evaporada por secamiento, podríamos decir:
A Ocurre una reacción de sustitución.
B Ocurre una reacción de neutralización.
C El producto es una sal y se denomina fosfato fosfórico.
D El producto es una sal y se denomina ácido fosfórico.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
