question 11 (3 points)
properties of some solutions
solution conductivity (electrical) color of litmus paper color of litmus after dipped in solution ph
1 very high red blue 10
2 low blue red 6.5
3 moderate red red 5.4
4 very high blue red 2
based on the information provided in this table, which solution is the strongest base?
explain your reasoning.

Explanation:

Step1: Recall base - properties

Bases turn red litmus blue and have a pH > 7. Higher the pH, stronger the base.

Step2: Analyze each solution

Solution 1: Turns red litmus blue and has pH = 10. Solution 2: Turns blue litmus red, so it's acidic. Solution 3: Keeps red litmus red, so it's acidic. Solution 4: Turns blue litmus red, so it's acidic.

Answer:

Solution 1
