To arrange the solutions in order of decreasing specific conductance, we need to understand the concept of specific conductance and how it relates to concentration.
Specific conductance is a measure of the ability of a solution to conduct electricity. It is influenced by the concentration of ions in the solution, as ions are responsible for carrying electric charge. In general, the higher the concentration of ions in a solution, the higher its specific conductance.
Now, let's arrange the solutions in order of decreasing specific conductance:
1. 0.5 M NaCl
2. 0.1 M NaCl
3. 0.05 M NaCl
4. 0.01 M NaCl
Explanation:
The 0.5 M NaCl solution has the highest concentration of ions, so it will have the highest specific conductance.
Next, the 0.1 M NaCl solution has a lower concentration of ions compared to the 0.5 M NaCl solution but higher than the remaining solutions.
Following that, the 0.05 M NaCl solution has a lower concentration of ions compared to both the 0.5 M NaCl and 0.1 M NaCl solutions.
Finally, the 0.01 M NaCl solution has the lowest concentration of ions, resulting in the lowest specific conductance.
Therefore, arranging the solutions in order of decreasing specific conductance, we have:
0.5 M NaCl > 0.1 M NaCl > 0.05 M NaCl > 0.01 M NaCl
The specific conductance of a solution is directly proportional to the concentration of ions in the solution. Therefore, the higher the concentration of ions, the higher the specific conductance.
So, we need to arrange the given solutions in order of decreasing concentration:
1. 0.5 M NaCl (highest concentration)
2. 0.1 M NaCl
3. 0.05 M NaCl
4. 0.01 M NaCl (lowest concentration)
Therefore, the solutions arranged in order of decreasing specific conductance are:
0.5 M NaCl > 0.1 M NaCl > 0.05 M NaCl > 0.01 M NaCl.
