A student tested a 0.1 M aqueous solution and made the following observations:
conducts electricity
turns blue litmus to red
reacts with Zn(s) to produce gas bubbles
Which compound could be the solute in this solution?
A. CH3OH.
B. LiBr.
C. HBr.
D. LiOH.

Respuesta :

Answer:

Correct option: C

Explanation:

the key point of given solution is , it turns blue litmus paper to red this means the unkown solution is acid and if it conducts electricity means it must dissociate in the solution so CH3OH will not be that because it will not dissociate in the solution only HBr dissociates in the solution and only HBr could give gas on reaction with Zn and that gas will be the hydrogen gas.
