Chapter 4: Problem 51

Write net ionic equations for the reaction, if any, that occurs when aqueous solutions of the following are mixed. a. ammonium sulfate and barium nitrate b. lead(II) nitrate and sodium chloride c. sodium phosphate and potassium nitrate d. sodium bromide and rubidium chloride e. copper(II) chloride and sodium hydroxide

Short Answer

Expert verified
a. \(Ba^{2+} (aq) + SO_4^{2-} (aq) 鈫 BaSO_4 (s)\) b. \(Pb^{2+} (aq) + 2 Cl^- (aq) 鈫 PbCl_2 (s)\) c. No reaction d. No reaction e. \(Cu^{2+} (aq) + 2 OH^- (aq) 鈫 Cu(OH)_2 (s)\)

Step by step solution

01

a. Ammonium sulfate and barium nitrate

Start by writing the reactants and products of the possible double replacement reaction: (Ammonium ion: NH鈧勨伜, Sulfate ion: SO鈧劼测伝, Barium ion: Ba虏鈦, Nitrate ion: NO鈧冣伝) NH鈧勨倐SO鈧 (aq) + Ba(NO鈧)鈧 (aq) 鈫 2 NH鈧凬O鈧 (aq) + BaSO鈧 (s) Since barium sulfate is insoluble, a reaction occurs. Now, write the net ionic equation by omitting the spectator ions (NH鈧勨伜 and NO鈧冣伝): Ba虏鈦 (aq) + SO鈧劼测伝 (aq) 鈫 BaSO鈧 (s)
02

b. Lead(II) nitrate and sodium chloride

Write the reactants and products of the possible double replacement reaction: (Lead(II) ion: Pb虏鈦, Nitrate ion: NO鈧冣伝, Sodium ion: Na鈦, Chloride ion: Cl鈦) Pb(NO鈧)鈧 (aq) + 2 NaCl (aq) 鈫 2 NaNO鈧 (aq) + PbCl鈧 (s) Since lead(II) chloride is insoluble, a reaction occurs. Write the net ionic equation by omitting the spectator ions (NO鈧冣伝 and Na鈦): Pb虏鈦 (aq) + 2 Cl鈦 (aq) 鈫 PbCl鈧 (s)
03

c. Sodium phosphate and potassium nitrate

Write the reactants and products of the possible double replacement reaction: (Sodium ion: Na鈦, Phosphate ion: PO鈧劼斥伝, Potassium ion: K鈦, Nitrate ion: NO鈧冣伝) Na鈧働O鈧 (aq) + 3 KNO鈧 (aq) 鈫 3 NaNO鈧 (aq) + K鈧働O鈧 (aq) Since all the compounds are soluble, no reaction occurs, and no net ionic equation needs to be written.
04

d. Sodium bromide and rubidium chloride

Write the reactants and products of the possible double replacement reaction: (Sodium ion: Na鈦, Bromide ion: Br鈦, Rubidium ion: Rb鈦, Chloride ion: Cl鈦) NaBr (aq) + RbCl (aq) 鈫 NaCl (aq) + RbBr (aq) Since all the compounds are soluble, no reaction occurs, and no net ionic equation needs to be written.
05

e. Copper(II) chloride and sodium hydroxide

Write the reactants and products of the possible double replacement reaction: (Copper(II) ion: Cu虏鈦, Chloride ion: Cl鈦, Sodium ion: Na鈦, Hydroxide ion: OH鈦) CuCl鈧 (aq) + 2 NaOH (aq) 鈫 2 NaCl (aq) + Cu(OH)鈧 (s) Since copper(II) hydroxide is insoluble, a reaction occurs. Write the net ionic equation by omitting the spectator ions (Na鈦 and Cl鈦): Cu虏鈦 (aq) + 2 OH鈦 (aq) 鈫 Cu(OH)鈧 (s)

Most popular questions from this chapter

You are given a \(1.50-\mathrm{g}\) mixture of sodium nitrate and sodium chloride. You dissolve this mixture into \(100 \mathrm{~mL}\) of water and then add an excess of \(0.500 \mathrm{M}\) silver nitrate solution. You produce a white solid, which you then collect, dry, and measure. The white solid has a mass of \(0.641 \mathrm{~g}\). a. If you had an extremely magnified view of the solution (to the atomic- molecular level), list the species you would see (include charges, if any). b. Write the balanced net ionic equation for the reaction that produces the solid. Include phases and charges. c. Calculate the percent sodium chloride in the original unknown mixture.

Some of the substances commonly used in stomach antacids are \(\mathrm{MgO}, \mathrm{Mg}(\mathrm{OH})_{2}\), and \(\mathrm{Al}(\mathrm{OH})_{3}\) a. Write a balanced equation for the neutralization of hydrochloric acid by each of these substances. b. Which of these substances will neutralize the greatest amount of \(0.10 \mathrm{M} \mathrm{HCl}\) per gram?

What volume of \(0.0521 \mathrm{M} \mathrm{Ba}(\mathrm{OH})_{2}\) is required to neutralize exactly \(14.20 \mathrm{~mL}\) of \(0.141 \mathrm{M} \mathrm{H}_{3} \mathrm{PO}_{4}\) ? Phosphoric acid contains three acidic hydrogens.

Douglasite is a mineral with the formula \(2 \mathrm{KCl} \cdot \mathrm{FeCl}_{2} \cdot 2 \mathrm{H}_{2} \mathrm{O}\). Calculate the mass percent of douglasite in a \(455.0-\mathrm{mg}\) sample if it took \(37.20 \mathrm{~mL}\) of a \(0.1000 \mathrm{M} \mathrm{AgNO}_{3}\) solution to precipitate all the \(\mathrm{Cl}^{-}\) as \(\mathrm{AgCl}\). Assume the douglasite is the only source of chloride ion.

Write net ionic equations for the reaction, if any, that occurs when aqueous solutions of the following are mixed. a. chromium(III) chloride and sodium hydroxide b. silver nitrate and ammonium carbonate c. copper(II) sulfate and mercury(I) nitrate d. strontium nitrate and potassium iodide
