New cards

adding OH- ions to solutions of metal aqua 3+ ions

produces insoluble precipitates of metal hydroxides

New cards
<p>in water metal aqua 3+ ions form the equilibrium</p>

in water metal aqua 3+ ions form the equilibrium

if you add OH- ions to the equilibrium, H3O+ ions are removed shifting equ right

3
New cards
<p>another equilibrium is now set up</p>

another equilibrium is now set up

OH- remove H3O+ ions from the solution pulling the equ right

4
New cards

this occurs one last time

leaving you with an insoluble uncharged metal hydroxide

all the metal hydroxide precipitates will dissolve in acid

they act as bronsted lowery bases and accept H+
