Question

This picture shows a light bulb connected to a batterywith the circuit interrupted by a solution.When dissolved in the water to form a 1.0 molarsolution, all of the following substances will completea circuit allowing the bulb to light except...O...hydrochloric acid....sucrose.O ...sodium nitrate.O...ammonium sulfate.

Answer 1

In this question, we need to evaluate the ability to form electrolytes from the given compounds in the question, this is because when a compound is considered to be a strong electrolyte, this means that it will give a lot of ions into the solution and make the solution conduct electricity, so from the given compounds we have:

HCl = is an acid and in a solution it will totally dissociate, being considered a strong electrolyte, therefore it will complete the circuit

Sucrose = is a nonelectrolyte, not dissociating and forming ions, therefore sucrose will not complete the circuit

NaNO3 = same case as HCl, strong electrolyte

(NH4)2SO4 = same case as HCl, strong electrolyte

Answer it will be Sucrose
