Concept explainers
You are given a solid mixture of NaNO2 and NaCl and are asked to analyze it for the amount of NaNO2 present. To do so, you allow the mixture to react with sulfamic acid, HSO3NH2, in water according to the equation
NaNO2(aq) + HSO3NH2(aq) →
NaHSO4(aq) + H2O(ℓ) + N2(g)
What is the weight percentage of NaNO2 in 1.232 g of the solid mixture if reaction with sulfa-mic acid produces 295 mL of dry N2 gas with a pressure of 713 mm Hg at 21.0 °C?

- Write a balanced equation for the reaction of hydroiodic acid, HI, with calcium hydroxide, Ca(OH)2. Then, write the balanced complete ionic equation and the net ionic equation for this neutralization reaction.arrow_forwardClassify each of the following reactions as a combination reaction, decomposition reaction, displacement reaction, or combustion reaction. a When solid calcium oxide, CaO, is exposed to gaseous sulfur trioxide, SO3, solid calcium sulfate, CaSO4, is formed. b Calcium metal (solid) reacts with water to produce a solution of calcium hydroxide, Ca(OH)2, and hydrogen gas. c When solid sodium hydrogen sulfite, NaHSO3, is heated, solid sodium sulfite, Na2SO3, sulfur dioxide gas, SO2, and water vapor are formed. d Magnesium reacts with bromine to give magnesium bromide, MgBr2.arrow_forwardPotassium permanganate (KMnO4) solutions are used for the determination of Fe2+ in samples of unknown concentration. As a laboratory assistant, you are supposed to prepare 500 mL of a 0.1000 M KMnO4 solution. What mass of KMnO4, in grams, do you need?arrow_forward
- A soluble iodide was dissolved in water. Then an excess of silver nitrate, AgNO3, was added to precipitate all of the iodide ion as silver iodide, AgI. If 1.545 g of the soluble iodide gave 2.185 g of silver iodide, how many grams of iodine are in the sample of soluble iodide? What is the mass percentage of iodine, I, in the compound?arrow_forwardWhat is the molarity of a solution of sodium hydrogen sulfate that is prepared by dissolving 9.21 g NaHSO4 in enough water to form 2.00-L solution? What is the molarity of each ion in the solution?arrow_forwardDetermine the volume of sulfuric acid solution needed to prepare 37.4 g of aluminum sulfate, Al2(SO4)3, by the reaction 2Al(s)+3H2SO4(aq)Al2(SO4)3(aq)+3H2(g) The sulfuric acid solution, whose density is 1.104 g/mL, contains 15.0% H2SO4 by mass.arrow_forward
- The final step in the manufacture of platinum metal (for use in automotive catalytic converters and other products) is the reaction 3 (NH4)2PtCl6(s) 3 Pt(s) + 2 NH4Cl(s) + 2 N2(g) + 16 HCl(g) Complete this table of reaction quantities for the reaction of 12.35 g (NH4)2PtCl6.arrow_forwardAn antacid tablet has calcium carbonate as the active ingredient; other ingredients include a starch binder. You dissolve the tablet in hydrochloric acid and filter off insoluble material. You add potassium oxalate to the filtrate (containing calcium ion) to precipitate calcium oxalate. If a tablet weighing 0.750 g gave 0.629 g of calcium oxalate, what is the mass percentage of active ingredient in the tablet?arrow_forwardAn unknown solid acid is either citric acid or tartaric acid. To determine which acid you have, you titrate a sample of the solid with aqueous NaOH and from this determine the molar mass of the unknown acid. The appropriate equations are as follows. Citric acid: H3C6H5O7(aq) + 3 NaOH(aq) 3 H2O(l) + Na3C6H5O7(aq) Tartaric acid: H2C4H4O6(aq)+ 2 NaOH(aq) 2 H2O(l) + Na2C4H4O6(aq) A 0.956-g sample requires 29.1 mL of 0.513 M NaOH to consume the acid completely. What is The unknown acid?arrow_forward
