Question 1

When an acid neutralizes a base, what type of compound is formed?

Accepted Answer

A salt

Question 2

Which of the following salts will produce a basic solution when dissolved in water?

Accepted Answer

Na$$_2CO$_3$$

Question 3

A solution of NH$$_4Cl in $$water is expected to be:

Accepted Answer

Acidic, because NH$$_4^+ is a $$weak acid and Cl$$^- is $$neutral

Question 4

Which rule is used to determine if a transition metal cation is acidic?

Accepted Answer

If the charge is $$\geq +2$$, it is acidic; if less than +2, it is neutral

Question 5

Which of the following compounds will produce a neutral solution when dissolved in water?

Accepted Answer

KCl

Question 6

Given the salt FeCl$$_3$$, what type of solution will it produce when dissolved in water?

Accepted Answer

Acidic, because Fe$$^{3+} is a $$highly charged transition metal cation

Question 7

Which of the following anions will make a solution basic when paired with a neutral cation?

Accepted Answer

CO$$_3$$^{2-}$$

Question 8

A solution of Ba(NO$$_3$$)$$_2 in $$water will be:

Accepted Answer

Neutral, because both Ba$$^{2+}$$ and NO$$_3^-$$ are neutral ions

Question 9

Which of the following is true about main-group metal cations?

Accepted Answer

If the charge is $$\geq +3$$, it is acidic; if less than +3, it is neutral

Question 10

Which of the following salts will produce an acidic solution when dissolved in water?

Accepted Answer

Al(NO$$_3$$)$$_3$$

Question 11

If a salt is formed from a strong acid and a strong base, the resulting solution will be:

Accepted Answer

Neutral

Question 12

Which of the following is a correct net ionic equation for the neutralization of HCl with NaOH?

Accepted Answer

$$\mathrm{H^+} + \mathrm{OH^-} \rightarrow \mathrm{H_2O}$$

Question 13

Which of the following compounds will produce a basic solution when dissolved in water?

Accepted Answer

NaF

Question 14

A solution of Co(HCO$$_3$$)$$_2 in $$water will be:

Accepted Answer

Basic, because HCO$$_3^- is a $$weak base and Co$$^{2+} is $$neutral

Question 15

Which of the following is true about positive amines?

Accepted Answer

They are acidic

Question 16

If a salt contains a negative ion from a weak acid, what type of solution will it produce?

Accepted Answer

Basic

Question 17

Which of the following is a correct method to determine if a salt will produce an acidic, basic, or neutral solution?

Accepted Answer

Analyze the acid-base properties of both the cation and anion

Question 18

A solution of Sr(HCO$$_3$$)$$_2 in $$water will be:

Accepted Answer

Basic, because HCO$$_3^- is a $$weak base and Sr$$^{2+} is $$neutral

Question 19

Which of the following salts will produce an acidic solution due to its cation?

Accepted Answer

CrCl$$_3$$
