Question

question 1
match up the solution with its qualitative concentration.
25% koh solution choose
0.15% koh solution choose
concentrated solution
dilute solution

Explanation:

To solve this, we analyze the concentration percentages. A concentrated solution has a relatively high amount of solute, while a dilute solution has a low amount. For KOH solutions:

• 25% KOH has a high solute percentage, so it's a concentrated solution.
• 0.15% KOH has a low solute percentage, so it's a dilute solution.

Answer:

25% KOH solution: concentrated solution
0.15% KOH solution: dilute solution
