Question

use the following information to answer the question: which solution is most likely hcl(aq)? use the following information to answer the questions. properties of tested solutions solution conductivity effect on red litmus paper effect on blue litmus paper ph 1 low changed to blue changed to red 13 2 high none none 7 3 high none changed to red 1 4 high none none 7 5 high none none 7 solution 1 solution 2 solution 3 solution 4

Explanation:

Step1: Recall properties of HCl(aq)

HCl(aq) is a strong acid. Strong - acids have high conductivity due to complete dissociation into ions in water. They turn blue litmus paper red and have a pH less than 7.

Step2: Analyze each solution

• Solution 1: Low conductivity and turns red litmus blue, so it's not HCl.
• Solution 2: High conductivity, but no effect on litmus papers and pH = 7, so it's not HCl.
• Solution 3: High conductivity, turns blue litmus red and has pH = 1 which is acidic. This is consistent with HCl properties.
• Solution 4: High conductivity, no effect on litmus papers and pH = 7, so it's not HCl.

Answer:

solution 3
