Final answer:
C) Non-electrolyte .A substance that doesn't produce ions in a solvent is defined as a non-electrolyte. These substances, such as sugar and ethanol, create non-conducting solutions, as opposed to weak acids or bases
Step-by-step explanation:
The definition of a substance that doesn't produce ions in a solvent, such as water, is a non-electrolyte. These substances create solutions that do not conduct electricity because they do not dissociate into ions when dissolved. Examples of non-electrolytes include molecular compounds like sugar or ethanol.
Unlike non-electrolytes, weak acids and weak bases partially dissociate into ions and are thus categorized as weak electrolytes. On the other hand, strong acids dissociate completely in water, producing a large number of ions, making them strong electrolytes.
In summary, the correct answer to the question about a substance that doesn't produce ions in a solvent is (C) Non-electrolyte. This distinction is important in understanding the conductivity of solutions and the chemical behavior of substances when they are dissolved.
