Question 1

An example of an acid-base neutralization is the reaction of

Accepted Answer

An acid-base neutralization is a reaction in which an acid and a base react to form a salt and water. In this case, the acid is H+ and the base is OH-. The products of the reaction are H2O and a salt, which is not shown in the equation.

Question 2

Which is the net ionic equation for the reaction that takes place when HClO₃(aq)is added to KOH(aq)?

Accepted Answer

The net ionic equation for the reaction that takes place when HClO3(aq) is added to KOH(aq) is H+(aq) + OH-(aq) → H2O(l). This is because the H+ and OH- ions react to form water, which is a neutral molecule. The other choices are incorrect because they do not represent the net ionic equation for the reaction.

Question 3

Which is the net ionic equation for the reaction that takes place when HNO₃(aq)is added to Mg(OH)₂(s)?

Accepted Answer

The net ionic equation involves only the species that undergo a chemical change. In this case, H⁺ from HNO₃ reacts with solid Mg(OH)₂ to form Mg²⁺ and water.

Question 4

ZnCO₃(s)is insoluble in water, but dissolves in excess 6.0 molar HCl(aq). Which equation best describes this reaction?

Accepted Answer

ZnCO₃ reacts with H⁺ ions from HCl to form Zn²⁺, water, and CO₂ gas.

Question 5

Which statement is NOT correct? Hint: Remember what the prefixes mean for each type of acid and how those effect salt formation.

Accepted Answer

A monoprotic acid can only donate one proton, so it cannot form acidic salts through partial neutralization.

Question 6

Complete neutralization of phosphoric acid with barium hydroxide yields Ba₃(PO₄)₂ as one of the products when it is separated and dried. This indicates the phosphoric acid is a

Accepted Answer

Phosphoric acid (H₃PO₄) is a triprotic acid, meaning it can donate three protons (H⁺ ions). The reaction with barium hydroxide (Ba(OH)₂) results in the formation of barium phosphate (Ba₃(PO₄)₂), which indicates that all three protons have been neutralized.

Question 7

One of the phosphoric acids when fully neutralized by treatment with barium hydroxide yields, as one of its products, a substance with the formula Ba₂P₂O₇. The parent acid for the anion in this compound is a Hint: Write the reaction and identify the formula of each species to help.

Question 8

Which reaction will yield NiCr₂O₇ as one of its products? Hint: Write each reaction and identify the name of each species present.

Accepted Answer

Question 9

What is the net ionic equation for the reaction that takes place when HClO₄(aq)is added to NH₃(aq)? Hint: Make sure to cancel out your spectator ions.

Accepted Answer

The net ionic equation involves the transfer of a proton (H⁺) from the strong acid HClO₄ to the base NH₃, forming NH₄⁺.

Question 10

What is the net ionic equation for the reaction that takes place when HC₂H₃O₂(aq)is added to Ba(OH)₂(aq)? Hint: Make sure to cancel out your spectator ions.

Accepted Answer

The net ionic equation involves the reaction of acetic acid (HC₂H₃O₂) with hydroxide ions (OH⁻) to form acetate ions (C₂H₃O₂⁻) and water (H₂O), with the spectator ions (Ba²⁺) being omitted.

Question 11

What is the net ionic equation for the reaction that takes place when HC₂H₃O₂(aq)is added to NH₃(aq)? Hint: Make sure to cancel out your spectator ions.

Accepted Answer

The net ionic equation involves the transfer of a proton from acetic acid (HC₂H₃O₂) to ammonia (NH₃), forming ammonium ions (NH₄⁺) and acetate ions (C₂H₃O₂⁻).

Question 12

What is the net ionic equation for the reaction that takes place when HNO₃(aq)is added to Fe₂O₃(s)? Hint: Make sure to cancel out your spectator ions.

Accepted Answer

The net ionic equation involves only the species that undergo a chemical change. In this reaction, H⁺ ions from HNO₃ react with Fe₂O₃ to form Fe³⁺ ions and water, without any spectator ions.

Question 13

What is the net ionic equation for the reaction that takes place when HCl(aq)is added to CaCO₃(s)? Hint: Make sure to cancel out your spectator ions.

Accepted Answer

The net ionic equation involves only the species that undergo a chemical change. In this reaction, HCl dissociates into H⁺ and Cl⁻ ions, and CaCO₃ reacts with H⁺ ions to form Ca²⁺, CO₂, and H₂O. The Cl⁻ ions are spectator ions and do not appear in the net ionic equation.

Question 14

What is the net ionic equation for the reaction that takes place when Ba(OH)₂(aq)is added to NH₄Cl(aq)? Hint: Make sure to cancel out your spectator ions.

Accepted Answer

The correct answer is A because it is the net ionic equation for the reaction that takes place when Ba(OH)2(aq) is added to NH4Cl(aq). The spectator ions are Ba2+ and Cl-.

Question 15

Which one of the following is NOT an example of an acidic salt?

Accepted Answer

Potassium hydrogen chloride is not a valid chemical compound. The other options are examples of acidic salts, which are formed from the partial neutralization of diprotic or polyprotic acids.

Question 16

Which is NOT an example of an acidic salt?

Accepted Answer

The answer of Which is NOT an example of an...

Question 17

The reaction, BaCl₂(aq)+ H₂SO₄(aq)$\rarr$ BaSO₄(s)+ 2 HCl(aq), is an example of a

Accepted Answer

This reaction is both a metathesis (double displacement) reaction and a precipitation reaction, as BaSO4 is formed as an insoluble solid.

Question 18

Which compound is insoluble in water?

Accepted Answer

Lead sulfate (PbSO₄) is insoluble in water, while the other compounds listed are soluble.

Question 19

Which compound is insoluble in water?

Accepted Answer

Calcium carbonate (CaCO3) is insoluble in water due to its strong ionic lattice and low solubility product.

Question 20

Which compound is soluble in water?

Accepted Answer

Magnesium chloride (MgCl₂) is soluble in water, while the other compounds listed are generally insoluble in water.
