Answer:

El yoduro de potasio es una sal cristalina de fórmula KI, usada en fotografía y tratamiento por radiación. Al ser menos higroscópica que el yoduro de sodio, es más utilizada como fuente de ion yoduro.

Explanation:Se porta como una sal simple. El ion yoduro, al ser un reductor débil, es fácilmente oxidado por otros elementos como el cloro para transformarse en yodo:

2 KI(ac) + Cl2(ac) → 2 KCl + I2(ac)

Tiene un pH neutro (pH = 7) ya que el catión potasio y el anión yoduro son iones espectadores, por lo que no reaccionan con el agua, manteniéndose inalterado el pH. El yoduro se oxida aún más fácilmente al formar ácido yodhídrico (HI), el cual es un reductor más fuerte que el KI. El yoduro de potasio forma el anión triyoduro(I3−) al combinarse con yodo elemental.

A diferencia del yodo, los triyoduros son altamente solubles en agua, por lo que el yoduro de potasio aumenta considerablemente la solubilidad del yodo elemental en agua, que por sí solo se disuelve en muy bajas cantidades.

HELP PLEASE<br>Explain why the elements of group 1 and 7 are quite reactive
Sauron [17]
Group 17 is the most readily reduced elements on the periodic table, meaning that they are so close to being a stable elements, only missing 1 electron to complete their valance electron shell. Thus they will essentially react with anything to get that last electron! 

Group 1 elements are extremely reactive because they are the most readily oxidized, they are very close to reaching stability by giving up only 1 electron. Thus they will react with almost anything to give up their electron.
