Label A-F based on the table using C for concentrated and D for dilute.
A $\square$ F
B $\square$
C $\square$
D $\square$
E $\square$
F $\square$
| acid/base | molarity | concentrated/dilute |
|---|---|---|
| HCI | 12 M | A |
| | 0.5 M | B |
| NaOH | 0.01 M | C |
| | 6.0 M | D |
| $H _2 SO _4$ | 0.05 M | E |
| | 10 M | F |
Answer (2)
Label each acid/base molarity as either concentrated (C) or dilute (D) based on typical lab concentrations.
12 M HCl is labeled as concentrated (C), and 0.5 M HCl is labeled as dilute (D).
6.0 M NaOH is labeled as concentrated (C), and 0.01 M NaOH is labeled as dilute (D).
10 M H2SO4 is labeled as concentrated (C), and 0.05 M H2SO4 is labeled as dilute (D).
The final labels are: A = C, B = D, C = D, D = C, E = D, F = C. A = C , B = D , C = D , D = C , E = D , F = C
Explanation
Understanding the Problem We need to label the molarities of the given acids and bases as either concentrated (C) or dilute (D). There are no explicit definitions of what molarity constitutes concentrated or dilute, so we will use common knowledge of typical concentrations in a laboratory setting.
Analyzing HCl Concentrations For Hydrochloric acid (HCl), 12 M is considered concentrated, while 0.5 M is dilute.
Analyzing NaOH Concentrations For Sodium hydroxide (NaOH), 6.0 M is concentrated, while 0.01 M is dilute.
Analyzing H2SO4 Concentrations For Sulfuric acid (H2SO4), 10 M is concentrated, while 0.05 M is dilute.
Final Labels Based on the above analysis, we assign the labels as follows: A = C (Concentrated) B = D (Dilute) C = D (Dilute) D = C (Concentrated) E = D (Dilute) F = C (Concentrated)
Examples
In a chemistry lab, understanding the concentration of solutions is crucial for conducting experiments accurately. Concentrated solutions are often used as stock solutions, which are then diluted to create solutions of desired concentrations for specific experiments. For example, a concentrated hydrochloric acid (HCl) solution might be used to prepare a dilute solution for titrating a base, ensuring precise measurements and reaction control. Knowing whether a solution is concentrated or dilute helps chemists handle chemicals safely and effectively, preventing hazardous reactions and ensuring reliable results.
The acids and bases are classified based on their molarity as concentrated (C) or dilute (D). The final labels are: A = C, B = D, C = D, D = C, E = D, F = C. This classification helps in understanding their properties and how they should be handled in a laboratory setting.
