n general terms, what are the spectator ions in a precipitation reaction? Why are the spectator ions not included in writing the net ionic equation for a precipitation reaction? Does this mean that the spectator ions do not have to be present in the solution?
Experiments show that propionic acid (CH3CH2COOH) is a weak acid. Write the chemical equation.
Write the net ionic equation for the reaction, if any, that occurs on mixing (a) solutions of sodium hydroxide and magnesium chloride. (b) solutions of sodium nitrate and magnesium bromide. (c) magnesium metal and a solution of hydrochloric acid to produce magnesium chloride and hydrogen. Magnesium metal reacting with HCl.
In each of the following cases, does a precipitation reaction occur when solutions of the two water-soluble reactants are mixed? Give the formula of any precipitate that forms, and write a balanced chemical equation for the precipitation reactions that occur. (a) sodium carbonate and copper(11) chloride (b) potassium carbonate and sodium nitrate (c) nickel(11) chloride and potassium hydroxide
Many over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.
Balance each of the following equations, and then write the net ionic equation. Show states for all reactants and products (s, . g, aq). (a) the reaction of sodium hydroxide and iron(II) chloride to give iron(II) hydroxide and sodium chloride (b) the reaction of barium chloride with sodium carbonate to give barium carbonate and sodium chloride (c) the reaction of ammonia with phosphoric acid
In each of the following cases, aqueous solutions containing the compounds indicated are mixed. Write balanced net ionic equations for the reactions that occur. (a) CaCl2 + Na3PO4 (b) iron(III) chloride and potassium hydroxide (c) lead(II) nitrate and potassium chloride
Complete the missing information in the following skeletion equation and balance the chemical equation: NaOH(aq)+3NaCl(aq)+Al(OH)3(aq)
Aqueous hydrogen fluoride (hydrofluoric acid) is used to etch glass and to analyze minerals for their silicon content. Hydrogen fluoride will also react with sand (silicon dioxide). (a) Write an equation for the reaction of solid silicon dioxide with hydrofluoric acid to yield gaseous silicon tetrafluoride and liquid water. (b) The mineral fluorite (calcium fluoride) occurs extensively in Illinois. Solid calcium fluoride can also be prepared by the reaction of aqueous solutions of calcium chloride and sodium fluoride, yielding aqueous sodium chloride as the other product. Write complete and net ionic equations for this reaction.
Azurite is a copper-containing mineral that often forms beautiful crystals. Its formula is Cu3(CO3)2(OH)2. Write balanced equation for the reaction of this mineral with hydrochloric acid.
Thioridazine, C21H26N2S2, is a pharmaceutical agent used to regulate dopamine (Dopamine, a neurotransmitter, affects brain processes that control movement emotional response, and ability to experience pleasure and pain.) A chemist can analyze a sample of the pharmaceutical for the thioridazine content by decomposing it to convert the sulfur in the compound to sulfate ion. This is then trapped as water-insoluble barium sulfate (see Figure 4.4). SO42(aq, from thioridazine) + BaCl2(aq) BaSO4(s) + 2 Cl(aq) Suppose a 12-tablet sample of the drug yielded 0.301 g of BaSO4. What is the thioridazine content, in milligrams, of each tablet?
Lead(II) nitrate reacts with cesium sulfate in an aqueous precipitation reaction. What are the formulas of lead(II) nitrate and cesium sulfate? Write the molecular equation and net ionic equation for the reaction. What are the names of the products? Give the molecular equation for another reaction that produces the same precipitate.
