1. How does the Key change for a weak acid?
Tema [17]

The weak acid will have fewer ions than the strong acid of similar concentration.

The chemical reactions for a weak acid and a strong acid is given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

<h3>What are strong and weak acids?</h3>

Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.

Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.

Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.

The equation of the dissociation of strong acids and weak acids are given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.

Explanation:

En el cuerpo humano, las células se organizan en tejidos, los cuales a su vez forman órganos y finalmente dichos órganos forman sistemas de órganos que llevan a cabo funciones de forma conjunta.

Los principlales sistemas de órganos y sus funciones son los siguientes:

- nervioso: controla los impulsos nerviosos, controlando tanto los movimientos voluntarios del cuerpo como también las funciones cognitivas.

-endócrino: regula diferente funciones del organismo (como por ejemplo, el crecimiento) a partir de la secreción de sustancias químicas denominadas hormonas

-circulatorio: encargado de llevar nutrientes y eliminar desechos de los tejidos a través de la sangre  

-digestivo: encargado de la obtención de nutrientes a través del proceso de digestión de alimentos

-respiratorio: intercambia gases con el medio exterior, obteniendo oxígeno y eliminando dióxido de carbono

-excretor: elimina los desechos del organismo

-reproductor: encargado de perpetuar la especies mediante el mecanismo sexual de reproducción

-muscular: responsable de los movimientos voluntarios e involuntarios  

-esquelético: provee un sostén físico a las diferentes partes del cuerpo  

-inmunológico: encargado de eliminar microorganismos patógenos

-linfático: también implicado en la defensa del organismo contra microorganismos patógenos  

-integumentario: provee una capa que protege al organismo de agentes externos como, por ejemplo, los rayos solares
