Indicate whether each of the following solutions is an acidic, a basic, or a neutral solution.
Drag the appropriate solutions to their respective bins.
[OH-] = 5.0 × 10^-12 M
[H30+] = 6.0 × 10^-12 M
[OH-] = 4.5 × 10^2 M
[H30+] = 1.4 × 10^-4 M
The first solution with [OH-] = 5.0 × 10^-12 M is an acidic solution.
The second solution with [H30+] = 6.0 × 10^-12 M is a basic solution.
The third solution with [OH-] = 4.5 × 10^2 M is also a basic solution.
The fourth solution with [H30+] = 1.4 × 10^-4 M is a neutral solution.
To determine whether a solution is acidic, basic, or neutral, we need to compare the concentrations of hydroxide ions ([OH-]) and hydronium ions ([H30+]).
1) [OH-] = 5.0 × 10^-12 M
This concentration of hydroxide ions is extremely low, indicating an acidic solution.
2) [H30+] = 6.0 × 10^-12 M
This concentration of hydronium ions is extremely low, indicating an acidic solution.
3) [OH-] = 4.5 × 10^2 M
This concentration of hydroxide ions is relatively high, indicating a basic solution.
4) [H30+] = 1.4 × 10^-4 M
This concentration of hydronium ions is relatively low, but still higher than the concentrations in the previous examples. This suggests a slightly acidic solution.
Based on these comparisons, we can categorize the solutions as follows:
- Solution 1: Acidic
- Solution 2: Acidic
- Solution 3: Basic
- Solution 4: Slightly acidic
To determine whether each solution is acidic, basic, or neutral, we need to analyze the concentrations of hydroxide ions ([OH-]) and hydronium ions ([H3O+]).
1) [OH-] = 5.0 × 10^-12 M:
The concentration of hydroxide ions is extremely low, suggesting that there are more hydronium ions than hydroxide ions present. This indicates an acidic solution.
2) [H3O+] = 6.0 × 10^-12 M:
Similarly, the concentration of hydronium ions is also extremely low, indicating that there are more hydroxide ions than hydronium ions present. Therefore, this solution is basic.
3) [OH-] = 4.5 × 10^2 M:
In this case, the concentration of hydroxide ions is relatively high, suggesting that there are more hydroxide ions than hydronium ions present. This indicates a basic solution.
4) [H3O+] = 1.4 × 10^-4 M:
Here, the concentration of hydronium ions is greater than hydroxide ions, implying an acidic solution.
Based on these analyses, we can classify the solutions as follows:
- Solution 1 is acidic
- Solution 2 is basic
- Solution 3 is basic
- Solution 4 is acidic
