Let Us Assume That Cr(OH)3(s) Is Completely Insoluble, Which Signifies That The Precipitation Reaction

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 0.450 L solution containing 0.0180 M of Cr3 (aq), and you wished to add enough 1.38 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. Part A Determine whether each of the following solutes is more soluble in hot water or cold water. Drag the appropriate items to their respective bins. Potassium cyanide is a toxic substance, and the median lethal dose depends on the mass of the person or animal that ingests it. The median lethal dose of KCN for a person weighing 115 lb (52.2 kg ) is 6.01×10−3 mol . What volume of a 0.0680 M  KCN solution contains 6.01×10−3 mol of KCN? Express the volume to three significant figures and include the appropriate units. Gastric acid pH can range from 1 to 4, and most of the acid is HCl. For a sample of stomach acid that is 9.80×10−3 M in HCl, how many moles of HCl are in 19.2 mL of the stomach acid? Express the amount to three significant figures and include the appropriate units. A 25.0 mL sample of an unknown HClO4 solution requires 44.3 mL of 0.110 M NaOH for complete neutralization. What was the concentration of the unknown HClO4 solution? The neutralization reaction is: HClO4(aq) NaOH(aq)→H2O(l) NaClO4(aq)
