Let us assume that cr(oh)3(s) is completely insoluble, which signifies that the precipitation reaction with naoh(aq) (presented in the transition) would go to completion.
cr3+(aq)+3naoh(aq) → cr(oh)3(s)+3na+(aq)
if you had a 0.600 l solution containing 0.0130 m of cr3+(aq), and you wished to add enough 1.26 m naoh(aq) toprecipitate all of the metal, what is the minimum amount of the naoh(aq) solution you would need to add? assume that the naoh(aq) solution is the only source of oh−(aq) for the precipitation.
express the volume to three significant figures and include the appropriate units.
