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.
If you had a 0.150 L solution containing 0.0160 M of Cr3+(aq), and you wished to add enough 1.30 M NaOH(aq) to precipitate 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.
